Safety Regulations and Hazard Assessments for Working Near Overhead Power Lines in Saskatchewan

This document outlines the safety regulations, hazard assessments, and required procedures for working near overhead power lines in Saskatchewan. It addresses clearance requirements, grounding procedures, and emergency response protocols to ensure worker safety and regulatory compliance.

General Safety Regulations

Occupational Exposure Limits

Saskatchewan has established occupational exposure limits (OELs) for various substances that workers may be exposed to. These limits are designed to protect workers from health hazards associated with exposure to these substances.

Specific OELs in Saskatchewan include:

OEL STEL (Short Term Exposure Limit): 20 mg/m³ for certain inhalable fractions and total dust.
OEL TWA (Time Weighted Average): 10 mg/m³ for certain inhalable fractions, total dust, and fumes.

These limits apply to substances such as Magnesium oxide (MgO), Calcium sulfate dihydrate, Limestone, and others. It is crucial to consult the specific safety data sheets (SDS) for each material to understand the applicable OELs and ensure compliance.

Engineering Controls and Personal Protective Equipment (PPE)

To minimize exposure to hazardous substances, implement appropriate engineering controls such as adequate ventilation, especially in confined areas. Ensure that emergency eye wash fountains and safety showers are readily available in the immediate vicinity of potential exposure.

Personal protective equipment (PPE) is essential for worker safety. This includes:

Wear protective gloves.
Wear protective clothing.
Wear protective goggles and face shield.
Use approved respiratory protection when exposure limits are exceeded or if irritation is experienced, especially in cases of insufficient ventilation or oxygen-deficient atmospheres.

Grounding Procedures

Proper grounding procedures are essential to avoid static electricity and prevent electrical hazards. Ensure all national and local regulations are observed regarding grounding.

Hazard Assessments

Risk Assessment

A thorough risk assessment should be conducted before commencing any work near overhead power lines. This assessment should identify potential hazards, evaluate the level of risk, and determine appropriate control measures.

Emergency Response Protocols

Emergency Procedures

Establish clear emergency response protocols in case of an incident involving overhead power lines. These protocols should include:

Immediate notification of emergency services and relevant authorities.
Evacuation procedures for personnel in the affected area.
First aid and medical assistance for any injured workers.
Procedures for isolating the work area and preventing further incidents.

Training and Competency

Ensure that all workers are adequately trained and competent to perform their tasks safely near overhead power lines. Training should cover:

Hazard identification and risk assessment.
Safe work practices and procedures.
Use of personal protective equipment.
Emergency response protocols.

Regular refresher training should be provided to maintain competency and ensure that workers are up-to-date with the latest safety regulations and procedures.

Additional Safety Measures

Ventilation

Ensure adequate ventilation, especially in confined areas, to minimize exposure to dust and fumes. This is particularly important when working with materials that may release hazardous particles into the air.

Hygiene Practices

When using any materials, do not eat, drink, or smoke in the work area to prevent ingestion of harmful substances. Maintain good personal hygiene practices, including regular handwashing.

Review and Updates

This safety document should be reviewed and updated regularly to reflect changes in regulations, procedures, or work practices. Ensure that all workers are informed of any updates and that they understand their responsibilities for working safely near overhead power lines.
