Under Cal/OSHA heat illness prevention rules for outdoor work, at approximately what temperature must the employer make shade available upon request and when workers take breaks?

Employers must provide access to shade when the outdoor temperature exceeds 80 degrees Fahrenheit, and it must be available for rest and recovery. Option a is the high-heat threshold (95 degrees) that triggers additional procedures, not the basic shade trigger. Option b waits for an emergency. Option d ignores the rule. Providing shade early helps prevent heat illness before symptoms appear.
