WHEN |
| Abrasive Blasting
Respirators |
Operators work in any of the
following situations: |
|
– Inside blast cleaning rooms |
|
– Where silica sand is used in
manual blasting operations |
|
– Where concentrations of toxic
dust exceed the permissible
exposure limits found in a
separate chapter: |
|
▪ Respiratory hazards, WAC 296-841-20020, Table-3
"Exposure Limits for Air
Contaminants" |
|
Exemption: |
|
• An abrasive respirator does
not need to be worn if the
operator is physically separated
from the nozzle and blast by an
exhaust ventilated enclosure. |
|
Definition: |
|
Abrasive-blasting respirator |
| |
A supplied air or a continuous
flow respirator constructed to
cover and protect the operator's
head, neck and shoulders from
rebounding abrasive. |
Eye and Face
protection to both of
the following:
– Blasting operators |
Respirators worn during blasting
operations do not provide eye
and face protection |
| – Personnel working
near blasting
operations |
|
| Gloves and Aprons
made of heavy
canvas or leather; |
Operators are exposed to the
impact of rebounding abrasives |
| OR |
|
| Equivalent protection |
|
| Notes: |
• Use only respirators certified by NIOSH in 42 C.F.R. Part 84 for protecting employees from dusts, and other hazards
produced during abrasive blasting operations, like: |
|
– Using a garnet sand to blast a concrete surface, resulting in crystalline silica dust |
|
• A filtering face piece may be used only for short, intermittent, or occasional dust exposures for any of the following
tasks: |
|
– To protect the operator during abrasive blasting operations performed outside the enclosure or outdoors where
nonsilica abrasives are used on materials with low toxicity |
|
– Clean-up |
|
– Dumping dust collectors |
|
– Unloading shipments of sand at receiving areas when the following controls are not feasible: |
|
▪ Enclosures |
|
▪ Exhaust ventilation |
|
OR |
|
▪ Other means |
