Which statement correctly differentiates a chemical hygiene plan (CHP) from a safety data sheet (SDS)?

• A. CHP provides hazard information and SDS is the safety plan.
• B. CHP is employer's plan for chemical safety, including procedures; SDS provide detailed chemical hazard information and handling instructions.
• C. CHP is a regulatory permit to work; SDS lists PPE.
• D. CHP describes environmental monitoring; SDS describes energy management.

Answer: (B)

Understanding the distinction between a chemical hygiene plan and a safety data sheet helps you see how workplaces manage safety versus how individual chemicals are described. A chemical hygiene plan is the employer’s program for chemical safety in the work environment. It lays out the procedures, practices, and controls the organization uses—how to handle chemicals safely, what training is required, how exposures are controlled, what medical surveillance or monitoring is needed, and how to respond to spills or emergencies. In short, it’s the overall plan a site follows to protect people.

A safety data sheet, on the other hand, is a product-specific document provided by manufacturers. It contains detailed hazard information for a particular chemical and practical handling instructions for that chemical—hazards, first aid, storage and ventilation considerations, required PPE, spill response, and exposure controls. It supports the plan by giving workers the exact information needed to work safely with each chemical.

So the best statement captures that the CHP is an employer’s plan with procedures, while the SDS supplies detailed hazard information and handling instructions for specific chemicals. The other options mix up what each document is meant to convey—for example, a plan isn’t a regulatory permit to work, and an SDS isn’t just PPE lists or a description of energy management.
