Hole Covers
Simple and effective when they're properly installed, rigid hole covers prevent workers from falling through skylights, temporary openings, and holes in walking-working surfaces.
OSHA requirements state hold covers must:
- support at least twice (2 times) the maximum expected weight of workers, equipment, and materials;
- be secured to prevent accidental displacement;
- have full edge bearing on all four sides; and
- be painted with a distinctive color or marked with the word HOLE or COVER.
Note: Skylights are not considered covers unless they meet this strength requirement.
Fences and Barricades
Fences, barricades and safety warnings are important in preventing injuries on a job site. Here are some best practices when setting them up:
- Risk Assessment: Before setting up any barricades or barriers, it's important to carry out a thorough risk assessment. Identify the hazards and decide where barriers need to be placed.
- Visibility: Barricades and barriers should be highly visible. This often means they are brightly colored (often yellow or orange) and may have reflective materials for low light conditions.
- Stability: Ensure that barricades are stable and secure so they can't be easily knocked over, ensuring they remain effective at all times.
- Proper Signage: Use signs and symbols that are universally recognized. Make sure that they are large enough and placed at the appropriate height to be easily seen.
- Appropriate Type of Barricade: Use the right type of barricade for the situation. For example, use light, portable barriers for temporary hazards and more substantial, permanent barricades for ongoing hazards.
- Access Points: Make sure that there are adequate access points for workers or emergency services if required. These should be clearly marked.
- Regular Inspection: Inspect the barricades regularly to ensure they are still in good condition and correctly positioned.
- Communication: Make sure all workers are aware of what the barricades signify and the importance of not bypassing them.
- Compliance: Ensure the barricades meet the standards and regulations set by the relevant safety authority in your country or region.
- Training: All employees should be trained on how to properly set up and dismantle safety barricades.
Remember, the primary purpose of safety barricades and warning barriers is to prevent accidents and protect workers. These best practices will help ensure they effectively serve that purpose.
