Aerial Lifts Safety


Aerial Lifts

Introduction: Aerial lifts are useful pieces of plant equipment when used properly. However, they combine height with mobility and can be extremely dangerous if misused.

 Main points:

  • Ensure the correct aerial lift is selected for the task (ground, height, SWL, etc).
  • Only suitably trained operators can use aerial lifts (must be trained for that specific item of plant equipment).
  • Continually monitor weather conditions.

 Discussion points:

  1. Assess ground conditions (uneven surface could result in the aerial lift overturning).
  2. Check for overhead obstructions (especially overhead power lines).
  3. Beware of collision with other vehicles, plant, equipment, scaffold etc., be particularly aware when using near public walkways and streets. Remember to allow for boom, arcs etc.
  4. Always check that the aerial lift is stable prior to use, deploy stabilizers, outriggers etc, as required.
  5. Any tools, materials etc., taken on board must be secured so far as is reasonably practicable to ensure they don’t fall from the edge.
  6. Operators employ safety harnesses as secondary fall protection.
  7. Never exceed Safe Working Loads.
  8. When maneuvering in tight areas or near public streets, ensure a Flagman is deployed.
  9. Refueling options (LPG, Diesel, etc). Refueling should take place in the open air where practicable, and the engine must be switched off.
  10. Any diesel spillages, etc., shall be cleaned up immediately.
  11. All aerial lifts must be subjected to thorough examinations at least once every six months, and shall be inspected before each operation by the operator with the findings recorded.



That all operators involved in the use of aerial lifts shall be familiar with how to operate the controls at the ground level as well as the main controls so as the platform can be brought safely to the ground in the event of an emergency situation. When working the aerial lifts, cherry pickers or other working platforms, it is essential that the operator has valid operator training.

Toolbox Talk Carbon Monoxide

Carbon Monoxide (CO)

 Carbon monoxide (CO) is a clear, odourless gas which is created by inefficient combustion emissions. The most common sources in industry are gasoline or diesel powered pressure washers, air compressors, forklifts or other petroleum fired machinery.

The chemical makeup of CO is a carbon (C) molecule linked to an oxygen (O) molecule. CO kills by binding up the haemoglobin in the blood. Since CO has an affinity for haemoglobin several hundred times greater than the affinity for O2, it takes only a small amount of CO to bind up a large amount of haemoglobin. This decreases the amount of O2 delivered to the tissues and without O2, you will slowly suffocate.

What does this mean for workers? Carbon Monoxide will affect workers as follows:

  1. Slight headache and dizziness
  2. Nausea
  3. Drowsiness and an euphoric feeling
  4. Unconsciousness
  5. Death

The level of CO mandated by OSHA as the maximum allowable for 8 hours is 50 parts per million (ppm). This is an extremely small amount of CO.

To prevent CO overexposure:

  1. Inspect the jobsite and remove any internal combustion machinery located near a hatch or other opening that may cause exhaust fumes to enter the space.
  3. Frequently monitor workspaces for CO with testing equipment and observe employees for signs of CO exposure.
  4. Train workers about the early symptoms of CO exposure.
  5. Insure the CO monitors in your offices and living areas are working.
  6. Co is IDLA (Immediately Dangerous to Life and Health) at 1200 ppm.
  7. Use CO monitors in confined space areas or areas with limited fresh air ventilation.


Toolbox Talk OSHA Signs & Tags

Do Your Signs and Tags Meet OSHA Specs?

OSHA says that its specifications for workplace safety signs and tags apply to the design, application, and use of all signs or symbols intended to indicate and define specific hazards.

 According to OSHA, all workplace safety signs must:0

  • Contain sufficient information to be easily understood.
  • Be concise, accurate and easy to read.
  • Identify the hazard.
  • Explain in a few words how to prevent accidents and injuries.
  • Be placed in prominent locations where workers can see them before they face the hazard.

You also need to be sure that your signs don’t themselves constitute a hazard. That’s why OSHA requires safety signs to have rounded or blunt corners and be free of sharp edges, burrs, splinters or other sharp projections. Also, the ends or heads of bolts or other fastening devices must be located in such a way that they can’t cause injury.

According to OSHA:

  • Tags should be used to warn of hazardous conditions, equipment, or operations when signs, guarding, or other positive means of protection can’t be used.
  • All required tags must contain a signal word—for example, “Danger,” “Caution,” or “Warning”—and a major message indicating the specific hazardous condition or the instruction to be communicated to the employee.
  • Danger tags should be used only in major hazard situations where an immediate hazard presents a threat of death or serious injury to employees.
  • Caution tags should be used only in situations where a non-immediate or potential hazard or unsafe practice presents a lesser threat of employee injury.
  • Warning tags may be used to represent a hazard level between Caution and Danger.
  • The signal word must be readable at a minimum distance of 5 ft. / 1.5 m or such greater distance as warranted by the hazard.
  • The major message should be presented in either pictographs, written text, or both.
  • Both the signal word and the major message must be understandable to all employees who may be exposed to the identified hazard.
  • Tags should be affixed as close as safely possible to their respective hazards by a positive means such as string, wire, or adhesive that prevents their loss or unintentional removal.
  • Tags should not be removed until such time as the identified hazard is eliminated or the hazardous operation is completed.
