In 2012, OSHA revised its OSHA Hazard Communication Standard (HCS) to create new compliance requirements for employers, including builders, apartment owners and managers.

The HCS requires all employers that use hazardous or toxic chemicals on their sites to label such products, maintain safety data sheets and conduct employee training. In apartment properties, commonly used operations and maintenance products like paints, adhesives, solvents and pool chemicals can trigger HCS compliance requirements.
