An accurate chemical inventory containing safety data sheets on all hazardous substances drives several other EHS programs. This includes ensuring first aid kits have the proper materials in them; spill response measures; handling and storage directions; exposure controls and proper personal protective equipment (PPE); physical and chemical properties that support the possible need for an eyewash station; determining which chemicals are incompatible with each other; disposal considerations for chemical spills; DOT information that identifies its DOT shipping class; and regulatory information that supports EPCRA Section 302, 312 and 313 reporting requirements. This session will examine what happened when a company had an inadequate hazard communication program that resulted in improper mixing of chemicals that created a lethal toxic gas, killing one and injuring 13 others. Attendees will learn why it’s essential to conduct value-added hazard communication training, have an accurate chemical inventory and know the hazards those chemicals present.
