PPE (Personal Protective Equipment)

that may be encountered. There are four categories of PPE:

o Boots, boot-covers
o Disposable protective suit

• Level B - Selected when the highest level of respiratory protection is necessary, but a lesser
level of skin protection is needed.
o Full face-piece SCBA
o Hooded chemical resistant clothing
o Gloves (inner/outer)
o Boots, boot-covers

• Level C - Selected when the concentration(s) and type(s) of airborne substances is known and
the criteria for using air purifying respirators are met.
o Full-face or half mask, air purifying respirator (NIOSH Approved)
o Hooded chemical resistant clothing
o Gloves inner/outer
o Boots, boot-covers

• Level D - A work uniform affording minimal protection.

On-site Monitoring

Monitor before initial entry to identify the IDLH condition. Be sure to put periodic monitoring in place
when the possibility of IDLH condition or flammable atmosphere has developed. Monitoring of high-
risk employees must be prioritized. After the actual clean-up phase commences, the employer shall
monitor those employees likely to have the highest exposures while on-site.

Employers shall develop and implement a program, which is part of the safety and health
program, to inform employees, contractors, and subcontractors (or their representative) of the
level and degree of exposure likely to occur.
