52 Abrasive Blasting

This document outlines safety procedures for abrasive blasting operations. It provides guidelines for personal protective equipment (PPE) to be used, including respirators, gloves, protective clothing, hearing protection and alarms to detect carbon monoxide levels. The PPE must be regularly inspected, cleaned and maintained. Medical questionnaires are required for all abrasive blasting workers. The air supply hoses and blasting equipment, such as nozzles, must also meet safety standards to prevent injuries from hoses whipping or disconnecting. Areas where blasting occurs must be barricaded and signed.

52. ABRASIVE BLASTING

A. GENERAL

This procedure provides guidelines to Contractors for protecting personnel engaged in shot,
sand, or other abrasive blasting operations.

B. PERSONAL PROTECTIVE EQUIPMENT (PPE)

The following PPE will be used or worn by personnel engaged in abrasive blasting operations:

• an air-line respirator of the continuous-flow type in a protective hood to cover the head
(protective helmet), neck, shoulders, and chest;
• an air-purifier and filter for removal of oil, water, and any other organic-matter
contaminant that might be discharged from the compressor;
• a pressure regulator with an attached gauge, if the pressure in the compressor exceeds
25 psi or equivalent;
• a pressure relief valve, if the pressure regulator should fail;
• an air-line hose of not more than three hundred (300) feet (90 meters) for each person;
• hood view ports made of impact-resistant safety glass, or plastic covered by a metal
screen;
• gauntlet-type leather gloves;
• hard leather work shoes (safety toes/steel shanks recommended);
• clothing made of strong-fibered material to resist flying abrasive material;
• an alarm system, which will automatically signal both audio and visual alarms if the
carbon monoxide (CO) level reaches 10 PPM; and
• adequate hearing-protection devices.

C. INSPECTION AND CARE OF PERSONAL PROTECTIVE EQUIPMENT (PPE)

Interiors of masks shall be cleaned daily. If a mask is worn by other than one (1) person, the
mask will be sterilized. All valves and regulators must be checked before each use. The
condensate (pet cock) valve at the bottom of the purifier should be opened daily to remove
excess water. (See respirator care and maintenance under "Occupational Health" in this
manual.) The air supply hood will be cleaned and stored as required for other respirators.

D. MEDICAL REQUIREMENTS

Personnel engaged in sand blasting operations must complete the medical questionnaire in the
Respirator procedure. This form will enable licensed medical professionals to determine if any
further action is necessary.

E. AIR SUPPLY / BLASTING EQUIPMENT

The airline hose will be a non-electrical conductor. Hose lengths will be joined by metal
couplings secured to the outside of the hose to avoid erosion and weakening of the couplings.

Nozzles will be attached to the hose by fittings that will prevent the nozzle from becoming
disengaged. Dead-man controls will be provided at the nozzle and on the hose.

Cable at least one-fourth (1/4) inch (6 millimeters) in diameter or safety chains will be
provided for and used on each hose connection to prevent the hose from whipping or thrashing
around in case a coupling becomes disconnected.

Hoses shall be non-compatible with other air hoses. Hoses must be capped or protected when
not in use.

The compressor shall have a receiver with thirty (30)-minute air supply.

Air samples shall be taken.

Sand blasting areas shall be barricaded with "SANDBLASTING AREA - KEEP OUT" signs.

Before each job, check hose-to-hose connections, hose-to-nozzle connections and hose-to-
mixing chamber.

NOTE!!! Review Material Safety Data Sheets (MSDS) for hazards associated with the
blasting material being used.
