Specific Job Tasks for Air Purifying Respirator
1.
Catalyst loading/unloading or other dust generating work may require the use of a
particulate filter.
2.
Spray painting may require the use of either the Scott-O-Vista or 3M 6000 series if the
gas or vapors exceed permissible levels (see MSDS).
3.
Welding and grinding on stainless or galvanized metals and welding in confined spaces
may require the use of 3M 8233 respirators. A supplied air line respirator will be
required where oxygen levels could be reduced to less than 19.5% or other toxic
materials may exceed allowable exposure limits.

includes:
∙
Work in or on product lines and vessels that contain hydrogen sulfide (H2S) gas.
∙
Tank or vessel entry.
∙
Work in inert or purged vessel.
∙

Revised 11/18/02
Emergency entry into equipment, vessels, tanks, or areas where unknown contaminant
levels or I.D.L.H. atmospheres may exist, may be performed with SCBA or supplied air
respirators equipped with escape bottle. These situations will include: rescue incidents,
fire fighting, spill response and cleanup, H2S or other leak situations.
NOTE: Procedures for entry into IDLH atmospheres. Refer to SHG #3, Safe Work Permit
Guidelines, section 5.5 Permitting for Confined Space.
7.0
Medical Evaluations
Employees who use or may use respirators will be medically evaluated to verify that they
are physically able to wear and use the respirators assigned prior to their first use. The
medical evaluation will be administered by the plant nurse before fit testing. The plant
nurse will be familiar with the stresses induced by the respirators under normal and
emergency conditions.
8.0
Respirator Selection
The Safety Department will identify and evaluate the respiratory hazard(s) in the
workplace. This evaluation shall include a reasonable estimate of employee exposures
to respiratory hazard(s) and an identification of the contaminant’s chemical state and
physical form.
9.0
10.0
Fit Testing and Training

Respirator users will be annually fit tested on all face piece styles available.
Records of the results for each individual tested will be maintained by the
Program Administrator.

Respirator users will be trained at least annually on the proper pre-use
inspection, use, care, cleaning, storage, and limitations of the respirators
available within the refinery. Operators and Emergency Response Team
members who have the potential to wear emergency use respirators will be
required to participate in donning drills to keep their familiarity with these
respirators at a high, proficient level.
Maintenance/Inspection/Storage
10.1
Cleaning and 1 Maintenance
Cleaning and Maintenance of reusable respirators is handled through the Safety
Department. A supply of clean face pieces and respirators will be maintained in
the Safety Department. All used respirators and face pieces will be returned to
the Safety Department for cleaning.

Pre-use Inspection

Respirator components should be inspected by the user prior to each
use. The following procedures should be followed:
(i)
Check the facepiece for cracks, tears and dirt.
(ii)
Examine exhalation valves and valve covers for signs of
distortion, cracking, or tearing. Lift valves and inspect valve seat
for dirt or cracking.
(iii) Make sure the head straps are intact and have good elasticity.
(iv) Examine all plastic parts for signs of cracking or fatigue. Make
sure the filter gaskets are properly seated and in good condition.

A positive and negative fit check should be performed prior to each use.
(See respirator instruction manual for proper procedure.)

A respirator with any damaged components should be brought to the
Safety Department for removal from service. A new respirator will then
be issued if necessary.
Storage

A respirator should be stored in a sealed plastic bag when clean and not
in use.

The cleaned and bagged respirator should be stored away from
contaminated areas when not in use.
Note: Respirators are not to be stored or left uncleaned and
unbagged in any area of the facility.
10.4 Supplied Air Quality Verification

Supplied air/breathing air cylinders must have on record a certificate of
analysis from the vendor. The cylinders will be tested by the Safety
Department staff for quality.

All supplied air breathing cylinders (2500 & 6000 psi) will be tagged
(ATTACHMENT 2) with inspector’s name and date. Thirty minutes
cylinders, one-hour SCBA cylinders and 5-minute escape bottles are
exempt from tagging.
