What does the Hazard Communication Standard (HazCom) require employers to provide about chemicals?
- a.Only a phone number
- b.A discount on the chemicals
- c.Nothing
- d.Labels, safety data sheets, and worker training about chemical hazards✓
The Hazard Communication Standard requires employers to inform and train workers about the hazardous chemicals they may be exposed to. This includes proper labeling, accessible Safety Data Sheets, and a written hazard communication program. Workers must be trained on how to protect themselves.
What is a Safety Data Sheet (SDS)?
- a.A vacation request
- b.A payroll form
- c.A building permit
- d.A document providing detailed hazard, handling, and emergency information about a chemical✓
A Safety Data Sheet provides detailed information about a hazardous chemical, including its hazards, safe handling, storage, first aid, and emergency measures. SDSs follow a standardized 16-section format. They must be readily accessible to workers on every shift.
How many sections does a standardized Safety Data Sheet contain under the Globally Harmonized System?
- a.3 sections
- b.5 sections
- c.16 sections✓
- d.50 sections
A standardized Safety Data Sheet contains 16 sections under the Globally Harmonized System of Classification and Labeling. The sections cover identification, hazards, composition, first aid, firefighting, handling, exposure controls, and more. This uniform format makes information easier to find.
What health hazard is associated with breathing respirable crystalline silica dust?
- a.Temporary sneezing only
- b.Improved lung function
- c.Better eyesight
- d.Silicosis, an incurable and sometimes fatal lung disease✓
Inhaling respirable crystalline silica dust can cause silicosis, an incurable and potentially fatal lung disease, as well as lung cancer and other illnesses. Silica is released when cutting, grinding, or drilling concrete, brick, and stone. Controlling dust at the source is critical to prevention.
Which is an effective engineering control to reduce silica exposure when cutting concrete?
- a.Holding your breath
- b.Cutting in an enclosed room with no ventilation
- c.Working faster
- d.Using water (wet methods) or local exhaust ventilation to suppress dust✓
Wet cutting methods and tools with local exhaust ventilation and vacuum dust collection are effective engineering controls that keep silica dust out of the air. These controls are preferred over relying on respirators alone. Reducing dust at the source protects everyone nearby.
When engineering controls cannot reduce silica below safe levels, what additional protection is used?
- a.A cloth bandana
- b.Sunglasses
- c.A properly selected and fit-tested respirator✓
- d.No protection
When engineering and work-practice controls cannot reduce silica exposure to acceptable levels, a properly selected and fit-tested respirator must be used. Respirators require a program including medical evaluation, fit testing, and training. They supplement, not replace, dust controls.
What is the purpose of a respirator fit test?
- a.To test breathing speed for fun
- b.To check the color
- c.To measure the worker's height
- d.To ensure a tight-fitting respirator seals properly to the wearer's face✓
A fit test verifies that a tight-fitting respirator forms an effective seal against the wearer's face so contaminants cannot leak in. It must be done before first use and periodically thereafter. Facial hair or an improper size can break the seal and defeat protection.
What is the best way to prevent back injuries when manually handling materials?
- a.Lift with a rounded back
- b.Use proper lifting technique, mechanical aids, and team lifting for heavy loads✓
- c.Lift the heaviest object alone quickly
- d.Twist while carrying
Back injuries are prevented by using proper lifting technique, keeping the load close, lifting with the legs, and avoiding twisting. Mechanical aids like carts and hoists and team lifting should be used for heavy or awkward loads. Planning the lift and clearing the path also reduce risk.
What is a symptom of heat exhaustion that workers should recognize?
- a.No symptoms at all
- b.Improved concentration
- c.Heavy sweating, weakness, dizziness, and nausea✓
- d.Feeling energetic
Heat exhaustion symptoms include heavy sweating, weakness, dizziness, headache, nausea, and clammy skin. Affected workers should move to a cool area, rest, and drink water. If symptoms worsen or confusion appears, it may signal heat stroke, a medical emergency.
What are the key elements of preventing heat illness on the job?
- a.Skipping breaks
- b.Wearing heavy dark clothing
- c.Water, rest, and shade✓
- d.Working nonstop in the sun
The key elements of heat illness prevention are water, rest, and shade, along with acclimatization for new or returning workers. Workers should drink water regularly, take breaks in shaded or cool areas, and watch for symptoms in themselves and others. Gradually building tolerance to heat is especially important.
What does an occupational noise exposure program aim to prevent?
- a.Faster work
- b.Noise-induced hearing loss through monitoring, controls, and hearing protection✓
- c.Better hearing
- d.Louder equipment
A hearing conservation program aims to prevent permanent noise-induced hearing loss. It includes noise monitoring, engineering and administrative controls, hearing protection, audiometric testing, and training. Hearing loss from noise is permanent but entirely preventable.
Which pictogram on a chemical label under GHS indicates a serious health hazard such as carcinogenicity?
- a.A smiley face
- b.A dollar sign
- c.A clock
- d.A human silhouette with a star-burst on the chest (health hazard symbol)✓
The GHS health hazard pictogram shows a human silhouette with a star-burst on the chest and warns of serious health effects such as carcinogenicity, respiratory sensitization, or organ toxicity. Recognizing GHS pictograms helps workers quickly understand chemical dangers. Each pictogram has a red diamond border.
What should a written hazard communication program include?
- a.A chemical inventory, labeling system, SDS access, and employee training plan✓
- b.Only the company logo
- c.Only a list of employees
- d.A lunch menu
A written hazard communication program must describe how the employer will maintain a chemical inventory, ensure containers are labeled, keep Safety Data Sheets accessible, and train employees. It ties together all elements of the HazCom standard. The program must be available to workers on request.
Why is it important to keep containers of hazardous chemicals properly labeled?
- a.To make them heavier
- b.To increase the price
- c.For decoration
- d.So workers can identify the contents and hazards and take proper precautions✓
Proper labeling ensures workers can quickly identify a chemical and its hazards so they can handle, store, and dispose of it safely. Labels must include the product identifier, signal word, hazard statements, and pictograms. Unlabeled or mislabeled containers are a serious and common violation.
What is the main hazard of working in a poorly ventilated area with solvents or fumes?
- a.Stronger materials
- b.Cooler temperatures
- c.Inhalation of toxic vapors that can cause illness or asphyxiation✓
- d.Better air quality
Poor ventilation allows toxic vapors, fumes, or gases to accumulate, which can cause illness, unconsciousness, or asphyxiation. Adequate ventilation, respiratory protection, and atmospheric monitoring reduce the risk. Solvent vapors may also create fire and explosion hazards.
What is 'acclimatization' in the context of working in hot environments?
- a.Gradually building the body's tolerance to heat over several days✓
- b.Wearing more layers
- c.Instantly working full shifts in heat
- d.Avoiding all water
Acclimatization is the process of gradually increasing a worker's exposure to heat over about one to two weeks so the body adapts. New workers and those returning from time off are at highest risk before they acclimatize. Many heat fatalities occur in a worker's first few days on the job.
How should hazardous materials generally be stored to reduce risk?
- a.In open buckets
- b.According to compatibility, with incompatible chemicals separated and containers labeled✓
- c.Mixed together to save space
- d.Near ignition sources
Hazardous materials should be stored according to their compatibility, keeping incompatible chemicals such as acids and bases separated to prevent dangerous reactions. Containers must be closed, labeled, and kept away from ignition sources where flammable. Safety Data Sheets provide storage guidance for each material.
What is the purpose of medical surveillance for workers exposed to certain health hazards?
- a.To replace ventilation
- b.To increase work hours
- c.To detect early signs of illness so exposure can be reduced before serious harm occurs✓
- d.To reduce wages
Medical surveillance monitors workers exposed to hazards such as silica, lead, or asbestos to detect early signs of illness. Early detection allows intervention before disease becomes serious or irreversible. It also helps evaluate whether workplace controls are effective.
Under OSHA's respirable crystalline silica standard for construction, what is the permissible exposure limit (PEL) as an 8-hour time-weighted average?
- a.There is no numeric limit as long as workers wear any dust mask
- b.500 micrograms per cubic meter, ten times the actual regulated limit
- c.50 micrograms per cubic meter of air✓
- d.5 milligrams per cubic meter measured only at the very end of the shift
29 CFR 1926.1153 sets the silica PEL at 50 micrograms per cubic meter (50 ug/m3) as an 8-hour TWA. Exposure above this level requires additional controls. Silica dust is released when cutting, grinding, or drilling concrete, brick, and stone.
What is the action level in OSHA's construction silica standard that triggers certain requirements such as exposure monitoring?
- a.25 micrograms per cubic meter as an 8-hour TWA✓
- b.The action level is the same as the permissible exposure limit exactly
- c.100 micrograms per cubic meter measured over any 15-minute period
- d.There is no action level defined anywhere in the silica standard
29 CFR 1926.1153 sets an action level of 25 ug/m3 as an 8-hour TWA, half the PEL, above which requirements such as exposure assessment and medical surveillance may apply. The action level provides a margin below the PEL. It helps ensure exposures are managed before they exceed the limit.
Table 1 of the construction silica standard allows an employer to:
- a.Substitute hearing protection for respiratory protection during cutting
- b.Follow specified control methods for a task instead of measuring exposure✓
- c.Skip all training as long as the task appears somewhere in the table
- d.Ignore silica dust entirely for any task listed in the table
Table 1 of 29 CFR 1926.1153 lists common construction tasks with specified engineering controls, work practices, and respiratory protection; employers who fully and properly implement the listed controls need not separately measure worker exposure. It simplifies compliance for common tasks. Controls such as water and vacuum dust collection are central to the table.
The construction silica standard requires each covered employer to have:
- a.Only a supply of disposable dust masks kept in the site office
- b.A written exposure control plan and a designated competent person✓
- c.A signed waiver from each worker accepting the risk of silicosis
- d.A single verbal warning given once at the start of the project
29 CFR 1926.1153 requires a written exposure control plan describing tasks, controls, and housekeeping, and designation of a competent person to implement it. The plan must be reviewed at least annually. The competent person makes frequent and regular inspections.
Under the silica standard, medical surveillance must be offered to employees who:
- a.Must wear a respirator under the standard for 30 or more days per year✓
- b.Request it for personal reasons unrelated to any silica exposure at work
- c.Have simply visited a construction site at any point during the year
- d.Work in any office role for the company regardless of dust exposure
29 CFR 1926.1153 requires the employer to make medical surveillance available to each employee who is required to use a respirator under the standard for 30 or more days per year. It includes a baseline exam, chest X-ray, and lung-function test. Early detection helps prevent progression of silica-related disease.
Which construction activity is a major source of respirable crystalline silica?
- a.Carrying finished lumber from a delivery truck to a storage rack
- b.Filling out injury and illness recordkeeping forms in the office
- c.Cutting, grinding, or drilling concrete, brick, or stone✓
- d.Reading printed blueprints in a climate-controlled site trailer
Silica dust becomes airborne when workers cut, grind, drill, crush, or abrade silica-containing materials such as concrete, brick, block, and stone, the activities regulated by 29 CFR 1926.1153. Controlling dust at the source with water or vacuum systems is the key protection. Dry cutting without controls produces the highest exposures.
A complete respiratory protection program under 29 CFR 1926.103 must include which core elements?
- a.A one-time signature confirming the worker owns a respirator
- b.Medical evaluation, fit testing, training, and maintenance✓
- c.Only handing out disposable masks whenever workers ask for them
- d.Nothing beyond posting a sign that reminds workers to breathe carefully
29 CFR 1926.103 incorporates 1910.134, which requires a written program with medical evaluation, fit testing for tight-fitting respirators, proper selection, training, maintenance, and program evaluation. Each element ensures the respirator actually protects the wearer. Respirators are used after engineering controls are applied.
Before a worker may be required to wear a tight-fitting respirator, they must first receive:
- a.A pay raise to compensate for the discomfort of wearing a mask
- b.A medical evaluation to ensure they can safely wear one✓
- c.A written test on the history of the respiratory protection standard
- d.Permission from every other member of the work crew on the site
Under 29 CFR 1910.134 (incorporated by 1926.103), a medical evaluation must be completed before fit testing or use, because respirator use can stress the heart and lungs. A physician or licensed health care professional reviews a questionnaire or exam. Workers found medically unable are not assigned tight-fitting respirators.
Why can facial hair along the sealing surface disqualify a worker from using a tight-fitting respirator?
- a.It makes the respirator too heavy for the worker to hold in place
- b.It prevents a proper face-to-facepiece seal, allowing contaminants to leak in✓
- c.It changes the color of the respirator and voids the manufacturer warranty
- d.It has no effect on the seal and is only a matter of company appearance rules
Facial hair that crosses the sealing surface of a tight-fitting respirator breaks the seal, letting contaminated air leak past the filter, so 29 CFR 1910.134 prohibits it for such respirators. A fit test cannot pass with an interfering beard. Loose-fitting powered respirators may be an alternative.
What are the two recognized methods for fit testing a tight-fitting respirator?
- a.Qualitative and quantitative fit testing✓
- b.Annual and monthly fit testing distinguished only by how often they occur
- c.Indoor and outdoor fit testing based only on where the worker stands
- d.Visual and verbal fit testing performed entirely without any equipment
29 CFR 1910.134 recognizes qualitative fit testing (relying on the wearer's taste, smell, or irritant response) and quantitative fit testing (using an instrument to measure leakage). Either method must be passed before use and repeated at least annually. The method chosen depends on the respirator and protection factor needed.
A filtering facepiece (N95) half-mask respirator has an assigned protection factor (APF) of:
- a.10✓
- b.1, meaning it provides no measurable reduction in exposure at all
- c.500, regardless of how the respirator is fitted to the wearer
- d.1,000, the same as a full self-contained breathing apparatus
OSHA's assigned protection factor table in 29 CFR 1910.134 gives filtering facepiece and other half-mask respirators an APF of 10, meaning they reduce exposure to about one-tenth if properly fitted. Higher-hazard exposures require respirators with higher APFs. The APF assumes a passing fit test and correct use.
In an atmosphere that is oxygen-deficient or immediately dangerous to life or health (IDLH), which respirator is required?
- a.A cloth face covering worn tightly against the nose and mouth
- b.No respirator, since low oxygen is not considered a real hazard
- c.An ordinary dust mask, which filters out low-oxygen conditions
- d.A supplied-air respirator or self-contained breathing apparatus (SCBA)✓
Air-purifying respirators only filter contaminants and cannot add oxygen, so oxygen-deficient or IDLH atmospheres require an atmosphere-supplying respirator such as a supplied-air respirator or SCBA, per 29 CFR 1910.134. Using a filter respirator in low oxygen can be fatal. Confined-space entries often require these devices.
When workers voluntarily use their own dust masks where exposures are below limits, the employer must still:
- a.Ignore the practice completely since voluntary use is unregulated
- b.Charge the worker a fee for each disposable mask they choose to wear
- c.Provide the information in Appendix D of the respirator standard✓
- d.Require a full medical exam and annual fit test for a paper dust mask
For voluntary use, 29 CFR 1910.134 requires the employer to provide users with the basic information in Appendix D, and for non-filtering-facepiece respirators, elements of the program still apply. This ensures voluntary use does not itself create a hazard. It balances worker choice with basic safeguards.
What is the permissible exposure limit for asbestos as an 8-hour time-weighted average?
- a.50 fibers per cubic centimeter measured only during active cutting
- b.There is no exposure limit for asbestos in construction work
- c.0.1 fiber per cubic centimeter of air✓
- d.1.0 fiber per cubic centimeter averaged over an entire 8-hour shift
29 CFR 1926.1101 sets the asbestos PEL at 0.1 fiber per cubic centimeter (f/cc) as an 8-hour TWA. A separate excursion limit applies to short-term exposures. Asbestos causes asbestosis, lung cancer, and mesothelioma.
In addition to the 8-hour PEL, the asbestos standard sets an excursion limit of:
- a.10 fibers per cubic centimeter averaged over any 12-hour period
- b.1.0 fiber per cubic centimeter averaged over 30 minutes✓
- c.There is no short-term limit, only the 8-hour average matters
- d.0.1 fiber per cubic centimeter averaged over a full 8-hour shift
29 CFR 1926.1101 sets an excursion limit of 1.0 f/cc averaged over 30 minutes, in addition to the 0.1 f/cc 8-hour PEL. The excursion limit controls brief high exposures. Regulated areas, wet methods, and negative-pressure enclosures help keep exposures below both limits.
Which diseases are most strongly associated with asbestos exposure?
- a.Temporary sneezing and mild watery eyes that clear within a day
- b.Improved lung capacity and increased resistance to respiratory infection
- c.Asbestosis, lung cancer, and mesothelioma✓
- d.Only minor skin irritation that resolves after washing with soap
Inhaled asbestos fibers can cause asbestosis (lung scarring), lung cancer, and mesothelioma, a cancer of the lining of the lungs or abdomen, as recognized in 29 CFR 1926.1101. These diseases often appear decades after exposure. There is no safe level of casual exposure, so controls are strict.
Which work practice is required (or prohibited) when disturbing asbestos-containing materials?
- a.Use wet methods and never dry-sweep or use compressed air on debris✓
- b.Dry-sweep the debris quickly to remove it before fibers settle
- c.Use compressed air to blow the dust away from the work area
- d.Allow the debris to dry out fully before disposing of it in the open
29 CFR 1926.1101 requires wet methods, HEPA vacuuming, and prompt cleanup, and prohibits dry sweeping and using compressed air, which would send fibers airborne. Debris is kept wet and sealed in labeled containers. Regulated areas limit access during the work.
What is the permissible exposure limit for lead in construction as an 8-hour TWA?
- a.30 micrograms per cubic meter, which is actually the action level
- b.50 micrograms per cubic meter of air✓
- c.There is no exposure limit for lead on construction projects
- d.500 micrograms per cubic meter averaged over a two-hour period
29 CFR 1926.62 sets the lead PEL at 50 ug/m3 as an 8-hour TWA. A separate action level triggers monitoring and other requirements. Lead exposure occurs during abrasive blasting, sanding, cutting, and welding of lead-painted surfaces.
The construction lead standard sets an action level of:
- a.200 micrograms per cubic meter measured only during welding
- b.50 micrograms per cubic meter, which is identical to the PEL
- c.There is no action level, only the permissible exposure limit
- d.30 micrograms per cubic meter as an 8-hour TWA✓
29 CFR 1926.62 sets the lead action level at 30 ug/m3 as an 8-hour TWA, which triggers exposure monitoring, training, and medical surveillance requirements. It is below the 50 ug/m3 PEL. Meeting the action level ensures protections begin before the PEL is exceeded.
Which activity is a common source of lead exposure in construction?
- a.Storing new, sealed cans of paint in a ventilated supply room
- b.Measuring a wall with a tape measure before any painting begins
- c.Sanding, cutting, or torch-burning surfaces coated with lead-based paint✓
- d.Reading the safety data sheet for a water-based latex paint indoors
Disturbing lead-based paint by sanding, grinding, cutting, abrasive blasting, or torch burning generates lead dust and fumes, the exposures regulated by 29 CFR 1926.62. Older structures commonly contain lead paint. Controls include containment, ventilation, wet methods, and respiratory protection.
Overexposure to lead can damage which body systems?
- a.None; lead is considered harmless once it is inside the body
- b.The nervous system, kidneys, blood, and reproductive system✓
- c.Only the eyes, causing brief blurring that resolves after resting
- d.Only the skin, causing a temporary rash that heals within hours
Lead is a systemic poison that can harm the nervous system, kidneys, blood-forming system, and reproductive system, and it can be carried home to families, as recognized in 29 CFR 1926.62. Effects can be chronic and irreversible. Blood-lead monitoring detects overexposure early.
To prevent 'take-home' lead exposure to workers' families, the lead standard requires:
- a.Bringing contaminated work clothing home to be laundered by family
- b.Skipping handwashing as long as gloves were worn during the task
- c.Hygiene practices such as washing and changing out of work clothes✓
- d.Eating meals in the immediate work area to save cleanup time
29 CFR 1926.62 requires hygiene facilities and practices, including handwashing, showering where required, and changing out of contaminated clothing, to prevent workers from carrying lead dust home. Contaminated clothing must not be taken home for laundering. These measures protect both workers and their families.
What is OSHA's permissible noise exposure limit for an 8-hour workday?
- a.90 decibels (A-weighted) as an 8-hour TWA✓
- b.60 decibels, roughly the level of a normal speaking voice
- c.There is no limit on workplace noise exposure in construction
- d.120 decibels averaged continuously over the entire work shift
29 CFR 1926.52 sets the permissible noise exposure at 90 dBA as an 8-hour TWA. Exposure above this requires feasible engineering or administrative controls and hearing protection. Prolonged loud noise causes permanent hearing loss.
Under OSHA's noise rules, permitted exposure time changes with level using an exchange rate of:
- a.1 decibel, so the permitted time barely changes as noise rises
- b.5 decibels (permitted time halves for each 5 dBA increase)✓
- c.20 decibels, so noise level has almost no effect on allowed time
- d.There is no relationship between noise level and permitted duration
29 CFR 1926.52(d) uses a 5-dB exchange rate: 90 dBA is allowed for 8 hours, 95 dBA for 4 hours, 100 dBA for 2 hours, and so on. Each 5-dB increase halves the permitted exposure time. Louder noise is tolerable only for shorter periods.
Occupational hearing loss from noise is best described as:
- a.Permanent and not medically curable, but preventable✓
- b.Beneficial, because it screens out distracting background sounds
- c.Temporary and always fully recovered after a single night of rest
- d.Reversible with over-the-counter medication taken after each shift
Noise-induced hearing loss is permanent and cannot be medically restored, which is why prevention through controls, hearing protection, and monitoring under 29 CFR 1926.52 and 1926.101 is essential. Damage accumulates gradually and often unnoticed. Once nerve cells are destroyed, hearing does not return.
When engineering and administrative controls cannot reduce noise below permissible levels, employers must:
- a.Simply advise workers to plug their ears with their fingers as needed
- b.Increase the noise so workers become accustomed to it more quickly
- c.Provide hearing protection such as earplugs or earmuffs✓
- d.Do nothing further, since hearing protection is entirely optional
29 CFR 1926.101 requires hearing protection (earplugs, earmuffs) when noise exceeds permissible levels and controls are insufficient. Protectors must be provided and fitted, and a hearing conservation program applies where required. They reduce the noise reaching the ear.
A GHS-compliant chemical label is required to contain how many core elements?
- a.Twelve: one element for each month the chemical will be stored on site
- b.Six: product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier information✓
- c.None; GHS labels only need the company logo and a barcode
- d.Two: the product name and the manufacturer's phone number only
Under the Hazard Communication Standard (29 CFR 1926.59, incorporating 1910.1200), a manufacturer/importer label must include the product identifier, signal word, hazard statement(s), pictogram(s), precautionary statement(s), and supplier identification. These standardized elements let workers quickly understand chemical hazards. Uniform labeling is a core feature of GHS.
On a GHS label, the signal word 'Danger' compared with 'Warning' indicates:
- a.Exactly the same severity, so the two words are interchangeable
- b.A more severe hazard than 'Warning'✓
- c.A less severe hazard, used only for very mild irritants
- d.That the product is completely safe and needs no precautions at all
Under 29 CFR 1910.1200, 'Danger' is used for the more severe hazard categories and 'Warning' for the less severe ones, and only one signal word appears on a label. The signal word quickly conveys relative severity. It works with the pictograms and hazard statements to inform the user.
How many hazard pictograms are defined under the Globally Harmonized System (GHS)?
- a.Three, one for each physical state of matter
- b.Fifty, one for every regulated chemical on a typical site
- c.Sixteen, matching the number of sections on a safety data sheet
- d.Nine✓
The GHS, as adopted in 29 CFR 1910.1200, defines nine hazard pictograms, each a red diamond containing a black symbol (for example flame, skull and crossbones, health hazard, corrosion). Eight are enforced under HazCom, plus the environmental pictogram. Recognizing them helps workers identify hazards at a glance.
The GHS flame pictogram on a chemical label indicates that the material is:
- a.Flammable✓
- b.Corrosive to skin and metal, and must be kept away from acids
- c.A compressed gas stored under high pressure in a cylinder
- d.An oxidizer that intensifies fire but does not itself burn
The flame pictogram under 29 CFR 1910.1200 identifies flammable materials (and related hazards such as self-heating or pyrophoric substances). It signals the need to keep the chemical away from ignition sources. Different pictograms cover corrosives, oxidizers, and compressed gases.
The GHS skull-and-crossbones pictogram warns of:
- a.An environmental hazard affecting fish but not people at the job site
- b.Acute toxicity that can cause serious harm or death from short exposure✓
- c.A mild skin irritant that only causes temporary redness on contact
- d.A material that is simply flammable and carries no toxic properties
The skull-and-crossbones pictogram under 29 CFR 1910.1200 warns of acute toxicity (severe), meaning short exposure can cause serious illness or death. It calls for strict controls and PPE. The exclamation-mark pictogram, by contrast, covers less severe irritant hazards.
The GHS corrosion pictogram indicates a chemical that can:
- a.Improve the durability of tools it comes into contact with
- b.Cause severe skin burns, eye damage, or corrode metals✓
- c.Only stain clothing without harming skin or eyes in any way
- d.Be safely handled with bare hands as long as it is diluted
The corrosion pictogram under 29 CFR 1910.1200 identifies chemicals that cause serious skin burns and eye damage or are corrosive to metals. These require chemical-resistant gloves, eye protection, and careful handling. Corrosives such as strong acids and bases must be stored separately.
