Final answer:
29 CFR 1910.22(a)(3) pertains to general requirements for workroom floors' maintenance, which must be kept clean, dry, and sanitary, not explicitly related to the provided answer choices on ladders, fire extinguishers, fall protection, or hazardous chemicals handling.
Step-by-step explanation:
29 CFR 1910.22(a)(3) specifies the general requirements for floors in the workplace under the Occupational Safety and Health Administration's (OSHA) General Industry standards. This regulation does not specifically address ladders, fire extinguishers, fall protection, or handling hazardous chemicals; rather, it sets forth basic guidelines to ensure that all workroom floors are maintained in a clean, dry, and, so far as possible, a sanitary condition.
The correct answer to the question 'What is stated in 29 CFR 1910.22(a)(3)?' is none of the options provided because it refers to floor maintenance rather than weight limits for ladders, fire extinguisher types, fall protection requirements, or procedures for handling hazardous chemicals. Options B, C, and D might be covered under other specific sections of OSHA standards but not under the referenced section.
For example, fall protection might be mentioned in OSHA standards that relate to specific working heights or activities. Employers are also required to provide training and ensure that health and safety standards are maintained, which can include knowing the location of safety equipment and handling hazardous materials with care.
