Site Specific Health & Safety Plan (HASP)
13.0 DECONTAMINATION PROCEDURES
An exclusion zone, contamination reduction zone, and support zone will be established, as
needed, when field personnel are using PPE. Decontamination station layout will be made on a
site-specific basis and will be based on the level of PPE used, the types of chemical hazards
encountered, and the site conditions, including topography, wind direction, and traffic patterns.
Defined site access and egress points will be established and personnel will enter and exit only
through these points. Generally, persons assisting in the decontamination station may be in one
level lower of respiratory protection than required in the work zone.
If personnel are in Level D-modified protection (no respirator but using protective gloves and/or
suits and other equipment), a portable decontamination station will be set up at the site. The
decontamination station will include provisions for collecting disposable PPE (e.g., garbage
bags); washing boots, gloves, vinyl rain suits, field instruments and tools; and washing hands,
face, and other exposed body parts. Used PPE and disposable equipment will be double-bagged
and placed in a municipal refuse dumpster on site. These wastes are not considered hazardous
and may be sent to a municipal landfill. Any PPE and disposable equipment that is to be
disposed of that is still reusable will be rendered inoperable before disposal in the refuse
dumpster.
Decontamination equipment may include:
• Plastic buckets and pails;
• Scrub brushes and long-handle brushes;
• Detergent;
• Containers of water;
• Paper towels;
• Plastic garbage bags;
• Plastic or steel 55-gallon barrels; and
• Distilled water.
If personnel are in Level C protection (respirator and using protective gloves and/or suits and
other equipment), a portable decontamination station will be set up at the site as described above
for Level D-modified protection. In addition, personnel should inspect, clean and disinfect,
repair, and properly store all respirators.
Respirators should be inspected before and after each use. Respirators reserved for emergency
use should be inspected on a monthly basis to ensure that they will perform satisfactorily.
Thoroughly check all connections on respirators to ensure that gaskets and “O” rings are in
place. Check for proper tightness. Check the condition of the facepiece assembly, the
connecting air tube and headbands. Inspect rubber or elastomer parts for pliability and signs of
deterioration. Maintain a record for each respirator inspection. Each inspection record should
include inspection date, inspector’s name, and any unusual conditions or findings.
Only a trained person with proper tools and replacement parts should work on respirators. No
one should ever attempt to replace components or to make adjustments or repairs beyond the
manufacturer’s recommendations.
Follow manufacturers’ storage instructions that are always furnished with new respirators or
affixed to the lid of the carrying case. In addition, these general instructions may be helpful:
