Which items must be provided at the decontamination site by the handler employer?

The correct response emphasizes the importance of a well-equipped decontamination site for handlers who may be exposed to hazardous materials. A properly set up decontamination site must include sufficient water, soap, towels, and a change of clothing because these items are critical for effectively cleaning and removing any harmful substances from the skin and clothing.

Water and soap are essential for washing off pesticides and other contaminants, while towels are necessary for drying off after washing. Additionally, having a change of clothing is crucial since contaminated clothing can pose an ongoing risk of exposure even after decontamination has occurred. This comprehensive setup ensures that handlers can effectively manage and mitigate any potential risks associated with pesticide exposure while maintaining their health and safety.

Other options reflect essential safety considerations, but they are not comprehensive enough to meet the full decontamination requirements. Personal protective equipment is critical for preventing exposure in the first place, and a first aid kit is important for emergencies but does not address the immediate need for decontamination after exposure. Therefore, the complete range of items listed in the correct response ensures a thorough approach to safety and health in a workplace that deals with potentially harmful substances.
