Published by SALUSPrime Contractor's Safety Responsibilities in Saskatchewan When a Single Trade Contractor Is Performing Construction Work =========================================================================================================================
In Saskatchewan, when a prime contractor oversees a construction worksite where a single trade contractor is performing work, the prime contractor bears significant legal duties and safety responsibilities to ensure compliance with occupational health and safety regulations. These responsibilities encompass supervision and oversight to protect the health and safety of all workers on the site.
Legal Duties and Safety Responsibilities
The core duties of the prime contractor revolve around establishing and maintaining a safe working environment. This includes, but is not limited to, the following:
- Hazard Assessment and Control: The prime contractor must identify existing and potential hazards at the worksite. Following identification, they are responsible for implementing control measures to eliminate or minimize the risks associated with these hazards. This proactive approach ensures that potential dangers are addressed before they can cause harm.
- Ensuring Compliance: The prime contractor is responsible for ensuring that all contractors and workers at the site comply with The Saskatchewan Employment Act and The Occupational Health and Safety Regulations, 1996. This involves communicating safety standards, verifying that workers have the necessary training and certifications, and enforcing safety rules.
- Coordination of Safety Activities: Even with a single trade contractor, the prime contractor must coordinate all safety-related activities on the worksite. This includes scheduling work to minimize risks, ensuring that different contractors are not exposed to each other's hazards, and holding regular safety meetings to discuss concerns and improvements.
- Supervision and Oversight: The prime contractor must provide adequate supervision and oversight to ensure that the work is being performed safely. The level of supervision required will depend on the nature of the work, the experience of the contractor, and the potential hazards involved. Regular inspections and monitoring are essential components of this duty.
- Emergency Preparedness: The prime contractor is responsible for developing and implementing an emergency response plan for the worksite. This plan should address potential emergencies such as fires, explosions, and serious injuries. Workers must be trained on the plan, and emergency drills should be conducted periodically.
- Communication: The prime contractor must establish and maintain effective communication systems to ensure that all workers are informed of potential hazards and safety requirements. This may involve posting safety notices, conducting toolbox talks, and using other communication methods to keep workers informed.
- Training and Competency: Verifying that the trade contractor and their employees possess the required training, certifications, and competencies to safely perform their work. This includes ensuring they are trained in hazard recognition, safe work procedures, and the proper use of personal protective equipment.
- Personal Protective Equipment (PPE): Ensuring that the single trade contractor uses appropriate personal protective equipment (PPE).
- Ventilation: Ensuring adequate ventilation, especially in confined areas. Emergency eye wash fountains and safety showers should be available in the immediate vicinity of any potential exposure.
In Saskatchewan, employers must ensure the safety of their workers by providing appropriate engineering controls, such as adequate ventilation, especially in confined areas, and by ensuring all national/local regulations are observed. Emergency eye wash fountains and safety showers should be available in the immediate vicinity of any potential exposure. Employers must also ensure workers wear protective gloves, clothing, and goggles and, when ventilation is insufficient, respiratory protection and face shields should be worn. Chemically resistant and corrosion-proof materials and fabrics should be used for protective clothing.
Specific Safety Measures
- Regular Site Inspections: Conducting routine inspections to identify hazards and unsafe practices.
- Toolbox Talks: Holding regular safety meetings to discuss specific hazards and safe work procedures.
- Enforcement of Safety Rules: Consistently enforcing safety rules and taking disciplinary action when necessary.
- Incident Investigation: Thoroughly investigating all incidents and near misses to identify root causes and prevent recurrence.
Occupational Exposure Limits
The following table outlines the Occupational Exposure Limits for various substances in Saskatchewan. These limits are crucial for maintaining a safe working environment and preventing health hazards associated with exposure to these substances. It is important to note that the table includes both OEL STEL (Short Term Exposure Limit) and OEL TWA (Time Weighted Average) values, which define the maximum permissible concentrations for short-term and long-term exposures, respectively.
| Substance | OEL Type | Limit (mg/m³) |
|---|---|---|
| Kaolin | OEL STEL | 4 mg/m3 (respirable fraction) |
| Kaolin | OEL TWA | 2 mg/m3 (respirable fraction) |
| Magnesium oxide (MgO) | OEL STEL | 20 mg/m3 (inhalable fraction) |
| Magnesium oxide (MgO) | OEL TWA | 10 mg/m3 (inhalable fraction) |
| Limestone | OEL STEL | 20 mg/m3 |
| Limestone | OEL TWA | 10 mg/m3 |
| Calcium oxide | OEL STEL | 4 mg/m3 |
| Calcium oxide | OEL TWA | 2 mg/m3 |
| Cement, portland, chemicals | OEL STEL | 20 mg/m3 |
| Cement, portland, chemicals | OEL TWA | 10 mg/m3 |
| Quartz | OEL TWA | 0\.05 mg/m3 (respirable fraction (Silica - crystalline (Trydimite removed))) |
| Sulfuric acid, calcium salt (1:1\) | OEL STEL | 20 mg/m3 (Gypsum and Plaster of Paris) |
| Sulfuric acid, calcium salt (1:1\) | OEL TWA | 10 mg/m3 (Gypsum and Plaster of Paris) |
| Particulates not otherwise classified (PNOC) | OEL STEL | 20 mg/m3 (insoluble or poorly soluble-inhalable fraction) 6 mg/m3 (insoluble or poorly soluble-respirable fraction) |
| Particulates not otherwise classified (PNOC) | OEL TWA | 10 mg/m3 (insoluble or poorly soluble-inhalable fraction) 3 mg/m3 (insoluble or poorly soluble-respirable fraction) |
The prime contractor must ensure adequate ventilation, especially in confined areas, and ensure all national/local regulations are observed. Emergency eye wash fountains and safety showers should be available in the immediate vicinity of any potential exposure. Personal protective equipment such as gloves, protective clothing, and protective goggles should be used. If ventilation is insufficient, respiratory protection should be worn. Chemically resistant materials and fabrics should be used for protective clothing. Wear protective gloves. Chemical safety goggles and face shield should be worn. Suitable protective clothing should be worn.
Conclusion
The prime contractor's role is critical in ensuring a safe and healthy worksite, even when only a single trade contractor is present. By diligently fulfilling their legal duties and safety responsibilities related to supervision and oversight, the prime contractor can significantly reduce the risk of accidents and injuries, fostering a culture of safety and compliance.
