Let's start with a brief overview of the six required elements of a hazard communication program. OSHA's hazard communication standard for construction (29 CFR 1926.59) references its general industry counterpart (29 CFR 1910.1200), so the requirements for both are identical.
Information about hazardous chemicals in the workplace, their potential hazards and the appropriate precautions must be communicated by an employer to all workers, including other employer's personnel and outside contractors who share the work site. This can be a key issue in the construction business.
