IMPORTANCE OF HARD HATS

"This alert was based on a NEAR MISS INCIDENT wherein a piece of concrete fell from a height of about approximately 50 ft (15m) and hit a worker below. The worker was wearing a hard hat at that time, otherwise it could have resulted to serious injury or even death. The size of the piece of concrete which fell was around the same size of a plumb stone and actually embedded itself on the side of the hard hat".



This incident illustrates the importance of wearing a hard hat and how serious the impact of not carrying out proper housekeeping can be.



IMPORTANT NOTES FOR HARD HATS:
The average of a SAFETY HARD HAT weighs about 14 oz. The average man's head weighs 14 lbs. So there's an ounce of safety for every pound of head - provided the head protection is properly worn and maintained.

Hard hats not only reduce the chances of serious injury resulting from falling objects, but it protects you also when you bump your head on things like machineries, ductworks, ceiling tie wires and forms. Non-conductive hard hats protect you from electrical shock and burns. Make sure that your hard hat is the right one to your job and MUST WEAR IT!

THERE WILL BE NO HELP UNLESS YOU WEAR IT. The hard hat is a very useful piece of safety equipment.

Don't take chances - wear your hard hat at all times, it protects your head and brain as well. Keep your hard hat always clean, in good condition and replace it immediately if it is damaged.

In case a head injury occurred, report immediately to your supervisor.



"Don't s" of Hard Hats:

  1. Properly adjust suspension systems to maintain clearance between your head and the shell of the hat.
  2. Don't cut holes for the purpose of ventilation.
  3. Don't substitute a "bump cap". They are not strong enough.
  4. Don't paint your hard hat.
  5. Don't put anything under it such as cigarettes, notebooks and the likes, except your head. 
  6. Don't wear it on a backward style.
Complaints Vs. Facts about Hard Hats:
  • "It's too heavy" - Hard hats are only a few ounces heavier than a cloth cap - the extra protection you get is worth the extra weight.
  • "It's too hot" - Measurements taken in hot weather show that the temperature under a hard hot often is cooler than it is outside.
  • "It gives me headache" - A thump on the head from something which was fallen from 2nd level floor will give you more even worse. There is no medical reason why a properly adjusted hard hat can cause a headache. Don't alter the suspension system or the hard hat as you won't get the desired or designed protection.
  • "It won't stay on" - You're right, it won't - in a high wind. A chin strap will solve the problem. Otherwise, you will find that a hard hat stays put no matter how much stooping or bending you have to do - if it's fitted properly.
  • "It's noisy" - That's your imagination. Tests shows that properly worn hard hats will shield your ears from noise to some extent.

SERIOUS INJURY ON ABRASIVE CUTTING WHEEL

A worker was cutting an aluminum roof using an angle granite grinder. Unexpectedly, the grinder's wheel broke into pieces and hit his face causing serious injury between somewhere his upper lips and nose (See photo below).


The injured person has given a first aid at site and then was sent to hospital for further treatment. The doctor at the hospital recommended that the injured person will be hospitalized for about two weeks.



Further Investigation: 

Type of Grinder tool used: Makita Grinder (Model 9006B)
Based on manufacturer specification, Makita grinder model 9006B recommended use, a 6" abrasive cutting wheel with a speed load of 10,000 rpm. But, the worker used a 9.5" abrasive cutting wheel, which was apparently over sized and allowed only to run at a speed of 3400 rpm.
The 9.5" abrasive cutting wheel was running at 10,000 rpm which was already over rated speed, causing the wheel broke apart and hit the worker's face.




ROOT CAUSE OF THE ACCIDENT:

  • The worker has been warned but ignored the advise or instruction.
  • Not using the required PPE -Face Shield or Face protection.
  • No safety guard was fitted on the grinding tool.
  • Improper use of the grinding machine. (Not following the Manufacturer's Recommendation).

ACCIDENT AT ELEVATED WORK PLATFORM

A man was working at a transport yard and had been transferring an elevated work platform (EWP) from the trailer of one truck to another, when the ramp that was used suddenly collapsed while he was driving.



The man fell with the elevated work platform (EWP), which was about more than a meter from the ground level. He was taken to the hospital and it was reported later he died as a result of his injuries.



ROOT CAUSE:

Ramps were placed (which were not designed for this purpose) across the gap between the two trailers (as shown in the above photo) and for a number of reasons, one ramp has failed or collapsed and the elevated work platform (EWP) rolled over the edge, causing a fatal to the operator.

PREVENTIVE MEASURES:
  • ALWAYS plan the work flow with the crew, (a job safety analysis or JSA) ensure that you have the correct equipment for the job and every member of the crew understands how the work will be carried out.
  • In case for some specific reason you do need to deviate from the Job Safety Analysis (JSA), then STOP the work, discuss, agree and then continue or proceed.
  • NEVER take any short cut methods with the Job Safety Analysis (JSA) or the equipment required for the work.
  • Ensure that all members of the workforce are qualified and competent for the work they going to carry out or assigned.


"Drivers & operators involved must be trained and competent. Risk assessment must be carried out to determine the risk involved to that specific task. Safe system of work should emerge from carrying out the Risk Assessment. Competent supervision must be in place and available to supervise any high risk task."
