SOP for Conducting Risk Assessments for Hazardous Chemicals

Standard Operating Procedure for Conducting Risk Assessments for Hazardous Chemicals

1) Purpose

The purpose of this SOP is to outline the systematic process for identifying, evaluating, and controlling risks associated with hazardous chemicals to ensure workplace safety, compliance with regulations, and protection of personnel and the environment.

2) Scope

This SOP applies to all departments handling hazardous chemicals, including laboratories, warehouses, and production units. It covers risk assessments for storage, handling, transportation, usage, and disposal of hazardous chemicals.

3) Responsibilities

Supervisors: Ensure risk assessments are performed for all hazardous chemical activities and processes.
Safety Officers: Conduct risk assessments, document findings, and recommend control measures.
Operators/Employees: Follow identified control measures and report unsafe conditions or processes.
Management: Review and approve risk assessment reports, allocate resources for mitigation, and monitor compliance.

4) Procedure

4.1 Preparation for Risk Assessment

Form a Risk Assessment Team:
1. Include the Safety Officer, supervisors, operators, and subject matter experts (if required).
2. Assign roles and responsibilities for data collection, analysis, and documentation.

Gather Relevant Information:
1. Collect the following documents:
  - Safety Data Sheets (SDS) of chemicals
  - Process flow diagrams
  - Equipment specifications
  - Incident/near-miss records
2. Identify the chemicals involved, their hazards, and quantities handled.
Identify Risk Assessment Criteria:
- Toxicity of the chemical
- Flammability, reactivity, and corrosivity
- Exposure routes (inhalation, skin, ingestion)
- Potential for environmental contamination
- Likelihood

of accidents (spills, leaks, explosions)

4.2 Conducting the Risk Assessment

Step 1: Hazard Identification
1. Identify hazards associated with each chemical, such as:
  - Health hazards: Toxicity, carcinogenicity, and sensitization
  - Physical hazards: Flammability, explosiveness, and reactivity
  - Environmental hazards: Water contamination, air pollution
2. Document identified hazards in the Hazard Identification Log (Annexure 1).

Step 2: Risk Evaluation
1. Evaluate risks based on:
  - Severity of consequences (injury, environmental damage, property loss)
  - Likelihood of occurrence (frequent, likely, unlikely, rare)
2. Use a Risk Matrix to assign a risk level (Low, Medium, High, Critical):

Likelihood / Severity	Minor	Moderate	Major	Critical
Frequent	Medium	High	Critical	Critical
Likely	Low	Medium	High	Critical
Unlikely	Low	Low	Medium	High
Rare	Low	Low	Low	Medium

Step 3: Risk Control Measures
1. Identify control measures following the hierarchy of controls:
  - Elimination: Replace the hazardous chemical with a safer alternative.
  - Substitution: Use chemicals with lower toxicity or reactivity.
  - Engineering Controls: Install fume hoods, ventilation systems, and chemical containment.
  - Administrative Controls: Develop SOPs, limit exposure times, and conduct training.
  - PPE: Use gloves, respirators, goggles, and chemical suits as required.
2. Document implemented controls in the Risk Control Log (Annexure 2).

4.3 Review and Approval

Submit the completed Risk Assessment Report to the Safety Officer for review.
Obtain approval from senior management before implementing control measures.
Distribute risk assessment findings to relevant personnel for awareness and compliance.

4.4 Monitoring and Review

Conduct periodic reviews of risk assessments:
- Annually or bi-annually
- After process changes, incidents, or near-misses
Update control measures based on new hazards, regulatory changes, or equipment upgrades.
Document all changes in the Risk Control Log.
