Emergency Response for Caught-In/Between Incidents
The Problem
Caught-in/between incidents are a leading cause of serious injuries and fatalities in the workplace. These occur when workers are caught in or compressed by equipment, materials, or collapsing structures. These situations often escalate quickly, and without a proper emergency response, they can result in life-threatening consequences. Today, we’ll discuss how to respond effectively to these incidents to save lives and prevent further harm.
Identify the Hazards
- Workers caught in moving machinery without proper guarding.
- Being pinned between heavy equipment and stationary objects.
- Collapse of trenches or excavation walls.
- Material shifting or falling, trapping workers beneath.
Safety Practices and Preventative Measures
Recognize Hazardous Situations
- Stay clear of moving equipment and never place yourself between machinery and a fixed object.
- Be aware of trench stability—never enter an unprotected trench.
- Secure materials to prevent shifting or toppling.
Prevent the Incident
- Use machinery with guarding in place and ensure it is maintained correctly.
- Follow CCOHS and provincial guidance for trench and excavation safety, including the use of trench boxes or engineered shoring systems.
- Wear high-visibility clothing when working near plant or equipment.
Emergency Response Steps
- Stop Work Immediately: Shut down any machinery or equipment involved in the incident.
- Call for Help: Notify emergency services (dial 911) or activate your site’s emergency response team.
- Secure the Scene: Keep others at a safe distance to avoid secondary injuries.
- Assist if Safe: If you are trained in first aid and the scene is safe, assist the injured person. Do not move them unless they are in immediate danger (e.g., further collapse risk).
- Follow Emergency Plans: Every site must have an emergency response plan. Know your responsibilities and follow procedures.
Post-Incident Actions
- Report the incident to your supervisor or health and safety representative.
- Document the events leading up to the incident.
- Participate in the incident review process to help identify causes and prevent recurrence.
Real-Life Case or Scenario
A worker in a trench was pinned by collapsing walls due to a lack of proper shoring. Co-workers quickly shut down all nearby machinery, contacted emergency services, and secured the area. Thanks to their prompt response and knowledge of emergency procedures, the worker was rescued and treated for non-life-threatening injuries. Their training and quick actions prevented a much more serious outcome.
Employee Responsibilities
- Recognize and report hazards related to machinery, trenches, or moving equipment.
- Avoid unsafe areas, such as unshored trenches or being positioned between operating equipment and structures.
- Know your role in the emergency response plan and be prepared to act.
Employer Responsibilities
- Provide appropriate guarding and protective systems for machinery and excavation work.
- Ensure workers are trained in hazard recognition and emergency response.
- Establish and communicate a clear emergency response plan for the worksite.
Discussion & Questions
- “What are some caught-in/between hazards you’ve seen on this site?”
- “Do you know the steps to take if someone is caught in or between equipment or materials?”
Encourage employees to discuss existing site practices and any concerns about hazards or emergency readiness.
Commitment/Action Plan
Let’s commit to identifying and reporting caught-in/between hazards before they lead to emergencies. Starting today, ensure you know your emergency response role and be ready to take action if an incident occurs.
Wrap-Up
Emergency response is critical in preventing fatalities and minimizing injuries. By recognizing hazards, taking preventive measures, and acting swiftly in emergencies, we can save lives and keep our worksite safe. Thank you for your attention and for making safety a shared priority.
Standards Overview
Under the Canada Labour Code and guidance from the Canadian Centre for Occupational Health and Safety (CCOHS), employers must eliminate or minimize the risk of serious harm, including caught-in/between incidents. CCOHS-aligned requirements include:
- The use of machine guarding and protective systems around hazardous equipment.
- Proper shoring, benching, or shielding in all trenches over 1.5 metres deep.
- Implementation of emergency response plans, including training and regular drills.
- Ongoing worker engagement and risk assessments around high-risk tasks.
