Protection Methods for Shot Blasting Machine

Shot blasting uses all kinds of abrasives to give a strong cleaning effect to surface using compressed air or water. It removes burrs instantaneously for texture application, peening or scraping. But the method warrants good protection with a high quality gear to save workers from the effects of hazardous dust and toxic metals that usually come out of the blasting hose.

How are they hazardous?

Working with abrasive media has two types of risks:

  • Noise Hazards
  • Health Hazards.

Noise hazards: Working with huge compressive force means there is high level of noise that can create significant hearing loss to the work and his comates. Abrasive blasting also gives high pitch sound. To counter this, hearing protection gear needs to be worn before every application as any noise greater than 85 dB must be controlled.

Health Hazards: Since there is a high degree of noise and dust, it comes in direct contact with humans and form health complications. Even the treated surface may contain toxic agents like fine lead paint, silica hazardous to workers. Most of these tiny substances like crystalline, coal and copper slag and steel grit commonly cause lung diseases, cancerous outcomes and major respiratory problems. Slags contain a high amount of toxins in the dust form like cadmium and arsenics.

Protection Comes as a Primary

Different shotblasting materials have different working conditions and each media involves unique treatment methods, however, with each type, health risk does follow. To implement them, a staff trained personnel must be authorized to substantiate action before cure comes as a necessity.

Some engineering requirements warrant working control and protective mechanisms during abrasive activities. These control points can be classified into engineering controls, administrative controls, including personal protection and respiratory protection.

These hygiene practices allow for better monitoring under the controls listed below:

Engineering Controls

Administrative Controls: Air cleaning machines that can even absorb micron particles in air are excellent cleaning mechanisms can be used to absorb the slightest of dust from the atmosphere.

Ensure proper cleaning and decontamination of tarps and equipment on the workplace.

Personal Protective Equipment:

Respiratory Protection: Since abrasives tend to stay under atmospheric pressure in the air, the worker must be properly covered in a face mask by helmet, full working attire covering his whole body and gloves. Govt. certified protection respirators are an added advantage from dust inhalation during operation.

Other Practices: In order to sustain good health, it is wise not to expose to the environment immediately after the shot blasting process. Care must be taken to prohibit eating or drinking openly in that environment. Avoid using tobacco products in blasting areas. Otherwise, for routine care and cleanliness, washing hands and face routinely is desired. Vacuum cleaning of contaminated work clothes and floors is an added advantage.
