All decisions on which protective level is most appropriate will be
made by the Incident Safety Officer. The level of protection selected
will be based on:
The type and (if measurable) concentration of the agent of
concern. This can be chemical, biological or physical agents.
Potential
for exposure to substances in the air, liquid splashes, or other direct
contact with various agents.
PPE Assessment
The Incident Safety Officer will have the Hazard Analysis from Section
3 of this HASP as a guide to PPE use for individual tasks. If a task
is
performed for which there is not a JHA, or the PPE must be modified from
that on the JHA, a PPE form is included for the Safety Officer to complete
(see Appendix 5-D)
Upgrading and downgrading of PPE
Deployment situations can be very dynamic. If air monitoring or other
forms of monitoring indicate a change of conditions, or any situation
arises that questions the effectiveness of current PPE levels, the Incident
Safety Officer will clear the area of concern, evaluate the situation
and make recommendations for further PPE if they deem necessary. The
monitoring and other findings will also be used to determine if changes
in work practices (such as work durations) are to be modified. See HASP
section 7 for further information on monitoring.
The Incident Safety Officer will also determine when PPE levels and
equipment can be downgraded due to safer conditions.
