•  Provide accommodations for end-of-shift 

showers and change areas with separate 
storage facilities for street clothes, protective 
clothing and equipment.

•  Keep contaminated clothing and equipment 

out of the clean change area. 

Respiratory Protection

An abrasive-blasting respirator must cover the 
wearer’s head, neck, and shoulders to protect 
the wearer from rebounding abrasive. Workers 
must use only respirators approved by 

NIOSH

 to 

provide protection from dusts produced during 
abrasive-blasting operations.

•  Type CE NIOSH-certified blasting airline 

respirator with positive pressure blasting 
helmet.  

Support personnel involved in cleanup and 
other related activities may also need respiratory 
protection. 

Personal Protective Equipment

•  Hearing protection
•  Eye and face protection
•  Helmet 
•  Leather gloves that protect to full forearm and 

aprons (or coveralls)

•  Safety shoes or boots

Worker Training and Hazard Communication

•  Provide training to abrasive blasters and 

support personnel on blasting health and 
safety hazards, how to use controls, personal 
hygiene practices, safe work practices and the 
use of PPE and respirators.

•  Manufacturers are required to include 

appropriate health hazard information on 
the blasting  materials on safety data sheets 
(SDS) as required under OSHA’s Hazard 
Communication standard (

29 CFR 1910.1200

).

•  Obtain and read the manufacturer’s SDS for 

health hazard information on the abrasive 
blasting material you are using.

For more information on abrasive blasting 
and control measures see: OSHA’s guidance 
document: 

“Abrasive Blasting Hazards in 

Shipyard Employment” (2006)

; and 

eTool: 

Mechanical Removers (Ship Repair)

.

When respirators are used, employers must 
establish a comprehensive respiratory 
protection program as required by the 
OSHA 

Respiratory Protection standard (29 

CFR 1910.134)

.

Disclaimer: This OSHA Fact Sheet provides a general overview of the requirements in OSHA standards related to abrasive blasting. 
It does not alter or determine compliance responsibilities in these standards or the 

Occupational Safety and Health Act of 1970

. Since 

interpretations and enforcement policy may change over time, the reader should consult current OSHA interpretations and decisions by 
the Occupational Safety and Health Review Commission and the courts for additional guidance on OSHA compliance requirements.
