1. Scope

This Safe Work Procedure (SWP) outlines the requirements for hazard communication, ensuring that all employees are informed about the chemical and physical hazards associated with the materials they work with. This procedure applies to all workplaces where hazardous chemicals are present and used. It covers the identification, labeling, Safety Data Sheets (SDS), training, and safe handling practices for hazardous materials.

2. Definitions

Hazardous Chemical: Any chemical which is a physical hazard or a health hazard [1].

Safety Data Sheet (SDS): A document that provides detailed information about a hazardous chemical, including its properties, hazards, and safety precautions [2].

Label: A written, printed, or graphic information displayed on or affixed to containers of hazardous chemicals [2].

3. Responsibilities

3.1 Supervisors

• Ensure that all hazardous chemicals are properly labeled [2].
• Maintain a current SDS for each hazardous chemical in the workplace [2].
• Provide training to workers on the hazards of chemicals and safe handling practices [3].
• Ensure workers have access to and understand SDSs [2].

3.2 Workers

• Read and understand the labels and SDSs for all hazardous chemicals they use [2].
• Use appropriate personal protective equipment (PPE) as required by the SDS or supervisor [1].
• Follow safe handling procedures to minimize exposure to hazardous chemicals [3].
• Report any incidents, near misses, or unsafe conditions to the supervisor [2].

3.3 Health and Safety Representative

• Assist in the development and implementation of the HazCom program [2].
• Conduct regular inspections to ensure compliance with the HazCom program [2].
• Investigate incidents and recommend corrective actions [2].

4. Potential Hazards and Risks

Hazard	Risk	Control Measures
Exposure to hazardous chemicals	Skin irritation, burns, respiratory issues, organ damage, cancer	Use appropriate PPE, follow SDS guidelines, ensure adequate ventilation, use proper handling techniques 1, 6
Dust inhalation	Respiratory irritation, silicosis, lung damage	Use respiratory protection, implement dust control measures, ensure adequate ventilation 1, 2
Eye contact with chemicals	Eye irritation, serious eye damage	Wear safety glasses or goggles, use face shields when necessary, ensure readily accessible eye wash stations 1, 2
Combustible dust	Explosion	Minimize dust generation and accumulation, provide adequate ventilation, eliminate ignition sources, use explosion-proof equipment 2, 5
Ingestion of hazardous chemicals	Nausea, vomiting, gastrointestinal irritation, poisoning	Do not eat, drink, or smoke while handling chemicals, wash hands thoroughly after handling 4, 6

5. Personal Protective Equipment (PPE)

Proper PPE must be worn to minimize exposure to hazardous chemicals 1, 2.

• Gloves - Wear suitable waterproof gloves to protect against skin contact with chemicals 1, 2.
• Eye Protection - Wear approved eye protection, such as dust- or splash-proof chemical safety goggles, and a face shield for additional protection 1, 2.
• Protective Clothing - Wear suitable waterproof protective clothing to prevent skin contact with hazardous materials 1, 2.
• Respiratory Protection - Use a NIOSH-approved dust mask or filtering facepiece in poorly ventilated areas or when exposure limits may be exceeded [4].

Inspect PPE before each use for damage. Replace damaged PPE immediately. Clean and maintain PPE according to manufacturer's instructions [2].

6. Equipment and Tools

• Ventilation Systems: Use adequate ventilation to keep airborne levels of dust, fume, vapor, etc., below recommended exposure limits 1, 2.
• Eye Wash Stations and Safety Showers: Provide readily accessible eye wash stations and safety showers in areas where chemical exposure is possible 1, 17.
• Non-Sparking Tools: Use non-sparking tools when handling flammable materials or in areas where combustible dust may be present [5].
• Dust Collection Systems: Use dust collection systems to minimize dust generation and accumulation [6].

Inspect all equipment and tools before each use. Ensure they are in good working condition. Remove any damaged equipment from service [2].

7. Pre-Job Requirements

7.1 Training and Competency

• Workers must be trained on the Hazard Communication Standard (HazCom) and the specific hazards of the chemicals they will be working with [3].
• Training must include information on how to read and understand labels and SDSs, proper handling procedures, and the use of PPE [2].
• Ensure workers are trained on the proper use and maintenance of ventilation systems and other engineering controls 1, 2.

7.2 Pre-Job Briefing

• Conduct a pre-job briefing to discuss the hazards associated with the task, the control measures that will be implemented, and the proper use of PPE [2].
• Review the SDSs for all chemicals involved in the task [2].
• Ensure all workers understand the emergency procedures [2].

7.3 Work Area Preparation

• Ensure the work area is clean and free of obstructions [3].
• Provide adequate ventilation to minimize exposure to airborne contaminants 1, 2.
• Ensure that eye wash stations and safety showers are readily accessible 1, 17.
• Implement measures to control dust generation and accumulation [6].

8. Safe Work Procedure Steps

Step 1: Chemical Identification and Labeling

• Verify that all containers of hazardous chemicals are properly labeled with the identity of the chemical, hazard warnings, and the name and address of the manufacturer [2].

• Do not use chemicals from unlabeled containers [2].

• Sub-step 1.1: Check the label for any missing or damaged information [2].

• Sub-step 1.2: If a label is missing or damaged, replace it immediately [2].

• Sub-step 1.3: Ensure that labels are legible and securely attached to the container [2].

Safety considerations for this step: Proper labeling is critical for identifying hazards and ensuring safe handling [2].

Step 2: Safety Data Sheet (SDS) Review

• Obtain and review the SDS for each hazardous chemical before use [2].

• Understand the hazards, safe handling procedures, PPE requirements, and emergency procedures outlined in the SDS [2].

• Sub-step 2.1: Locate the SDS for the chemical being used [2].

• Sub-step 2.2: Read and understand all sections of the SDS, paying close attention to hazard information, PPE requirements, and first aid measures [2].

• Sub-step 2.3: Ask your supervisor if you have any questions about the SDS [2].

Safety considerations for this step: SDSs provide detailed information necessary for safe chemical handling [2].

Step 3: Safe Handling and Storage

• Handle hazardous chemicals in accordance with the instructions provided on the label and in the SDS 4, 6.

• Use appropriate PPE to minimize exposure 1, 2.

• Store chemicals in properly labeled containers in a well-ventilated area, away from incompatible materials 2, 4.

• Sub-step 3.1: Use appropriate engineering controls, such as ventilation, to minimize exposure 1, 2.

• Sub-step 3.2: Avoid generating dust or aerosols when handling chemicals 2, 4.

• Sub-step 3.3: Clean up any spills immediately and dispose of waste properly 13, 15.

Safety considerations for this step: Proper handling and storage prevent accidents and minimize exposure 4, 6.

9. Precautions and Safety Measures

• Minimize Dust Generation: Implement measures to minimize dust generation and accumulation, especially when working with materials that can create combustible dust 2, 5.
• Ensure Adequate Ventilation: Use ventilation systems to keep airborne levels of dust, fume, vapor, etc., below recommended exposure limits 1, 2.
• Use Proper PPE: Always wear the appropriate personal protective equipment (PPE) as specified in the SDS for each chemical 1, 2.
• Practice Good Housekeeping: Maintain a clean and orderly work area to prevent the accumulation of dust and other hazardous materials 4, 15.
