Particulates, gases, and vapors are a hazardous substance and can put any person at great risk. Because of this reason, a person should wear appropriate safety eyewear along cloth and other safety gears if they are near to their working site. For the selection of safety gears, it is easy to select them if you know well your working site hazards. There are four levels of personal protective eyewear.
Level A protection:
Level A protection is required when you are working in the most hazardous environment and your skin, eyes, and respiratory need extra protection.
- Outer and inner chemical-resistant gloves.
- Disposable protective boots, gloves, and suite.
- Positive pressure supplied air respirator with escape SCBA.
- Complete encapsulated vapor and chemical protective suite.
Level B protection:
Such type of level needs the highest level of respiratory protection and skin protection need at a lesser level. It is included hazards waste site, vapors, or gas. Level B protection contains.
- Boots for outer chemical resistant.
- Hooded clothing for chemical resistant.
- Face shield
- Chemical resistant gloves
- Breathing apparatus SCBA
Level C protection:
Such kind of level need when the concentration and airborne constituents are involved and need air-purifying respirators.
- An entire face respirator for air purifying
- Chemical resistance gloves
- Hard hat
- Chemical resistant boots
Level D protection:
Level D need minimum protection and hazards level of work is not included. Suitable Level D safety requirements need
- Face shields
- Chemical Resistant Boots
While all the above are general guidelines for conventional equipment in specific conditions. Another combination of safety equipment can be more proper but depending upon the site requirements.
