For any safety hazard, whether physical, chemical or mechanical, there are often several options from which to choose. Three main methods to control hazards are:

  • Administrative controls that dictate specific ways a potentially  hazardous task is done. This usually will require additional worker  training and supervision.
  • Personal Protective Equipment or PPE. The PPE itself can often  present some potential hazards to the worker and require constant  monitoring of worker condition and equipment suitability. For example,  fall protection equipment, such as harnesses, lanyards and D-rings,  require both monthly inspections and pre- and post-use inspections to  identify damage and wear. Damaged or worn components must be taken out  of service immediately. Replacement is usually necessary. If repair is  possible, certified vendors must do the work.
  • Elimination of the hazard by replacement or substitution. This method is best used for dangerous or toxic chemicals and liquids.

However, there is a fourth option that should be considered carefully.

Engineering controls effectively reduce hazards

More reliable than administrative controls and PPE solutions, engineering controls have many advantages.

If designed into new and remodeled construction or processes,  engineering controls are very cost effective. In most instances,  expenses incurred during installation are minimal. Some engineering  controls can save time and money during their lifetime because of reduced maintenance costs.

However, there are cases when choosing the incorrect control adds  significantly to both installation costs, and ongoing use and  maintenance charges. For example, there are several options to remove  maintenance hazards from outdoor pole lighting.

For standard lighting on elevated platforms and catwalks, and for  material handling conveyors, the usual heights are 8, 10 and 13 feet  (2400, 3000 or 4000mm) from walk surface. Luminaires or fixtures  designed for these heights are standardized for optimal candlepower or  lumen output.

However, maintaining these fixtures requires the use of equipment to  raise the worker to the height of the unit. In many cases, PPE must also  be employed to protect the maintenance technician from injury as a  result of falling.

Even so, there are engineering options that eliminate the hazard without costly PPE or additional equipment.

Bring the fixture to the worker… not the worker to the fixture

There are two, simple methods to bring the lighting fixture to the  worker without additional safety equipment. Both methods can be included  in the initial design and construction of a facility. And they can also  be installed as conversions after the fact.

The first method is to shorten the pole height. For example, by using  a 6- or 7-foot (1800–2100mm) pole, the fixture is brought into reach of  most maintenance and repair technicians. The luminaire can be serviced  without the need for ladders, fall protection gear or other equipment  necessary to raise the worker.

However, this method presents several major concerns.

First, since light output does not fall straight down but in either a  conical circle or rectangle, the effective area a single fixture  illuminates is reduced. To illuminate the same area, installing  additional fixtures is necessary. This not only adds to the cost of  installation, but to the energy consumption of the system.

Secondly, this arrangement, while safer, could have significant ergonomic ramifications as well.

Even with the fixture lowered within reach, the maintainer must work  with arms raised, hands above the head. This position places stress on  the arms, shoulder joints and muscles, and on the neck and back muscles.

A final consideration is that the lower lighting fixtures can cause glare points, hampering workers’ vision in some cases.

A better way to “lowering the lights”

Instead of installing shorter lighting poles, and more of them, use a  pole that is the correct height for optimal illumination. The improved  pole, which can be installed as an OEM item, actually lowers the fixture to a comfortable, safe and ergonomic height for repair.

This type of solution employs a 45⁰ clutch-style swivelling joint.  One technician can lower the pole easily, eliminating the need for  additional workers. Ladder, fall protection/arrest systems, scaffolding  or other lifting devices are not needed. The benefits of this type of  system are enhanced safety, lower maintenance costs and a rise in  overall efficiency.

Here’s how it works.

The fixture is lowered to a height somewhere between the worker’s hip  and lower chest. This means that repair and maintenance work is done  with arms down, slightly extended forward and with the hands working on a  level plane. This is the recommended position for a safe, ergonomically  sound workstation, according to most ergonomics standards.

The strain on the shoulders, neck and back are removed, allowing the  technician to perform maintenance and repair comfortably, efficiently  and more easily. To see this type of safe, easy to use system in action,  click here for a short video.

While using this solution as part of a new construction or design is favorable, conversion kits can be used to upgrade the existing lighting support to the safer, more ergonomic design.

Carefully think through any hazard abatement design

As can be seen by this simple example, the benefits and potential  consequences of any hazardous work reduction must be carefully thought  out.

All aspects of the proposed change should be carefully evaluated.  It’s possible that while the change does solve the unsafe condition, it  may still cause others that need to be resolved.
