Appendix T1 Required
Personal Protective Equipment (PPE) for
Cryogen Work |
||
|
|||
Specific personal
protective equipment (PPE) is required
when handling cryogens. This appendix
describes how to determine the appropriate PPE, and how to obtain it.
This appendix applies only to PPE required to handle and dispense cryogens in amounts less than 50 gallons (190 liters). Additional control measures, up to and including a work control document, may be required for greater quantities or as otherwise indicated by a Task Hazard Analysis.
The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6550 Cryogenic Safety Program.
NOTE: Management authority may be delegated at the discretion of the responsible manager.
3.1
Everyone Working with Cryogens
·
Wear required PPE while working with cryogens.
·
Inspect PPE for damage before use; dispose
of unusable PPE in trash.
·
Obtain
PPE supplies as needed.
3.2
Supervisor/Technical
Representative (TR)/Sponsor
· Ensure availability of required PPE.
· Authorize only specifically trained individuals to work with cryogens in excess of 50 gallons (190 liters).
The potential for serious injury to eyes, hands, skin, and body from even minimal contact with cryogens makes the following PPE necessary.
Eye protection is required when working with cryogenic
gases and fluids.
·
Wear goggles if using amounts less
than 1-liter.
·
Wear a full face shield
over goggles if any of the following exists:
o
Using amounts greater than 1-liter,
o
Pouring cryogens
o
Working with a wide-mouth dewar.
·
Any exceptions to these requirements are to be
specified in an approved OSP or TOSP.
NOTE: A face shield by itself does not provide adequate splash protection. Goggles must be worn underneath. The only exception is a combination face shield/goggle unit. This can be obtained from Industrial Hygiene. |
Hand protection is
required when working with cryogens.
·
Wear cryogenic gloves these are
specifically made for handling cryogenic material.
NOTE: Never
wear clean room gloves which are absorbent (cotton) or porous (nylon) when
handling cryogens;
these gloves can worsen an injury. |
Protective clothing is
required when working with cryogens.
·
Always wear:
o
Long, cuffless, pants and
o
Closed-toed, leather or
otherwise impervious, shoes.
AND
·
When working with
quantities greater than 1-liter and less than 190-liters, wear:
o
Boots; and
o
Cryogenic apron.
NOTE: Never
wear shorts. Exposed skin is
particularly susceptible to serious injury. |
Required PPE is available through Webstock, the stockroom,
your supervisor, or Industrial Hygiene. (See ES&H Manual 6620
Appendix T1 Selecting, Acquiring, Training, and Caring for Personal Protective
Equipment for further information.)
