Typically composed of coveralls made from lightweight materials, Level D suits provide basic protection against dirt, debris, and mild irritants, making them suitable for a variety of general work environments.
Level D suits do not require any respiratory protection as they are meant for situations where there is no risk of inhalation of harmful substances. However, they may still include basic features such as goggles, gloves, and hard hats for additional personal protection. These suits are often used in situations like maintenance work, cleanup of spills where hazards have been mitigated, or in environments where chemicals are not present.
The use of Level D suits is prevalent in industries such as construction, agriculture, and waste management, where workers may encounter low-risk materials. According to the Bureau of Labor Statistics (BLS), a significant percentage of workplace injuries in these sectors can be linked to inadequate protection. Thus, even at this level, proper training and awareness of hazards remain relevant for ensuring safety.
When utilizing Level D suits, organizations should conduct regular training to ensure employees understand the importance of identifying hazards, even if they are perceived as low risk.
