Personal Protective Equipment (PPE) for Safe Grinding Operations

Grinding operations pose several risks, including flying particles, intense light, and potential chemical exposures. To mitigate these hazards and prevent injuries, specific personal protective equipment (PPE) is required. This document outlines the necessary PPE for safe grinding operations and their appropriate use.

Eye and Face Protection

Eye and face protection is paramount during grinding to protect against flying particles, dust, and potential chemical splashes. The following PPE is essential:

• Safety Glasses with Side Shields or Goggles: Always wear safety glasses with side shields or goggles when grinding a workpiece if you are not wearing a welding helmet. These protect against flying particles and debris.
• Face Shield: In addition to safety glasses or goggles, a face shield provides extra protection against splashes and larger debris.
• Welding Helmet: When grinding after welding, and a welding helmet is available, it can be used for grinding. Welding helmets provide protection from radiation, flying particles, debris, hot slag, sparks, intense light, irritation, and chemical burns. Welding helmets should be fitted with a filter shade suitable for the grinding task.

The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation. The employer shall ensure that each affected employee uses eye protection that provides side protection when there is a hazard from flying objects. Detachable side protectors (e.g. clip-on or slide-on side shields) meeting the pertinent requirements of this section are acceptable. [2] [2]

Eye and face protectors should have distinctive markings to identify the manufacturer and their class. [1]

Hand Protection

Hand protection is crucial to prevent cuts, abrasions, and burns during grinding operations. The following PPE is recommended:

• Gloves: Wear suitable waterproof gloves to protect hands from abrasion and potential contact with chemicals or sharp edges. Leather gloves with ballistic nylon reinforcement can offer a good grip and absorb some vibration.

Skin and Body Protection

Protecting the skin and body from sparks, hot debris, and chemical exposure is important. Recommended PPE includes:

• Protective Clothing: Wear suitable waterproof protective clothing to shield the skin from sparks and debris.
• Aprons: Flame-resistant aprons can provide an additional layer of protection, especially when grinding in a fixed position.

Respiratory Protection

Grinding can generate dust and fumes, which can be harmful if inhaled. Respiratory protection is necessary in such environments:

• Dust Mask or Filtering Facepiece: A NIOSH-approved dust mask or filtering facepiece is recommended in poorly ventilated areas or when permissible exposure limits may be exceeded.
• Respirator: In situations with high dust or fume concentrations, a respirator with appropriate filters (N100, R100, or P100) should be used.

Respirators should be selected by and used under the direction of a trained health and safety professional following requirements found in OSHA's respirator standard (29 CFR 1910.134) and ANSI's standard for respiratory protection (Z88.2). [4]

Foot Protection

Protecting feet from falling objects and sharp debris is essential:

• Safety Shoes: Wear heavy, well-fitted safety work boots approved by standards like CAN/CSA Standard Z195-14 (R2019): Protective Footwear.
• Cut-Resistant Boots: Chain saw operators should wear boots made from cut-resistant materials that offer protection from contact with running chain saws. Boots made of ballistic nylon offer the best cut protection.

Hearing Protection

Grinding operations can generate high noise levels, necessitating hearing protection:

• Ear Muffs or Ear Plugs: Use CSA-approved hearing protection devices, such as ear muffs or ear plugs, to protect against noise levels between 95 to 115 dBA.

General Safety Practices

• Regular Inspection: Defective or damaged personal protective equipment shall not be used.
• Proper Fit: Select PPE that properly fits each affected employee.
• Training: The employer shall provide training to each employee who is required to use PPE. Each such employee shall be trained to know when PPE is necessary, what PPE is necessary, how to properly don, doff, adjust, and wear PPE, the limitations of the PPE, and the proper care, maintenance, useful life and disposal of the PPE.
• Hygiene: Avoid breathing product; avoid skin and eye contact. Wash hands after handling.

Defective or damaged personal protective equipment shall not be used. [3]

The employer shall provide training to each employee who is required by this section to use PPE. Each such employee shall be trained to know at least the following: When PPE is necessary; What PPE is necessary; How to properly don, doff, adjust, and wear PPE; The limitations of the PPE; and, The proper care, maintenance, useful life and disposal of the PPE. [3]

Locations of PPE

PPE should be stored in easily accessible locations throughout the work area. Suggested locations include:

• Designated PPE Stations: Centralized stations near grinding areas for easy access.
• Tool Cribs: Larger facilities may have tool cribs where PPE is distributed.
• Individual Lockers: For personal items like safety glasses and gloves.

Conclusion

Adhering to these PPE guidelines is crucial for ensuring a safe working environment during grinding operations. Regular training, proper maintenance, and consistent use of PPE will significantly reduce the risk of injuries.
