What is a common method of ensuring safety when handling hazardous materials?

Wearing appropriate personal protective equipment (PPE) is essential for ensuring safety when handling hazardous materials. PPE acts as a barrier between the individual and potential hazards, such as toxic substances, chemicals, or infectious agents. It includes items like gloves, masks, goggles, and protective clothing that are specifically designed to prevent direct exposure to these harmful materials.

When individuals use PPE correctly, it significantly reduces the risk of injury or exposure, allowing them to carry out their tasks more safely. This practice is a cornerstone of occupational safety and health standards, highlighting that personal protection is a proactive measure to combat the dangers associated with hazardous materials.

The other choices focus on alternatives that do not provide the same level of protection. Learning first aid techniques, while beneficial, does not prevent exposure to hazardous materials but prepares one for response after an incident has occurred. Leaving materials exposed for ventilation might improve air quality, but it could also lead to accidental exposure or contamination in the surrounding area. Using any available cleaning substance is unsafe, as some cleaning agents may react adversely with hazardous materials rather than neutralizing them, leading to potentially dangerous situations.
