Mechanical Hazards

 

Overview

Each piece of machinery has its own unique mechanical and non-mechanical hazards. Machines can cause severe injuries: amputations, fractures, lacerations, or crushing inju­ries. Machines can also cause minor injuries such as bruises, abrasions, sprains or strains, burns, or cuts.

Mechanical hazards

Examples of mechanical hazards that can hit, grab, or trap an operator are: ·         hazardous motions. ·         points of operation. ·         pinch points and shear points. ·         There are different types of hazardous mechanical motions and actions: ·         hazardous motions such as rotating parts, reciprocating parts, or traversing parts. ·           hazardous actions such as cutting, punching, shearing, or bending.

Non-mechanical hazards

There are also non-mechanical hazards that can injure operators, including flying chips, splashes, sparks, or sprays that are created when the machine is running.

Operating instructions

Follow the machine’s operating instructions to ensure that the machine is being run cor­rectly and safely. Understand how the machine works, and you will reduce your risk of injury.

Lead Operations and Standards

 

Pure lead (Pb) is a heavy metal. It can combine with various other substances to form numerous lead compounds.

If absorbed into your body in certain doses, lead is toxic. It can be absorbed by breathing it in and through your mouth. As exposure continues, and if not filtered by the body and excreted, lead is stored in increasing amounts causing irreversible damage to body cells, organs, and whole body systems.

Long term (chronic) overexposure to lead may result in severe damage to the blood-forming, nervous, urinary, and reproductive systems.

OSHA’s lead standard

OSHA’s lead rule for construction workers sets the permissible exposure limit (PEL) at 50 micrograms per cubic meter of air as an 8-hour time weighted average. An action level is set at 30 micrograms per cubic meter calculated as an 8-hour TWA. The action level is the level at which your employer must begin certain compliance activities outlined in the standard.

Who does the standard apply to?

The rule applies to all construction work where an employee may be exposed to lead, all inor­ganic lead compounds, and organic lead soaps. Some operations that generate lead dust and fume include:

·         Flame-torch cutting, welding, the use of heat guns, sanding, scraping, and grinding of lead painted surfaces in repair, reconstruction, dismantling, and demolition work.

·         Abrasive blasting of bridges and other structures containing lead-based paints.

·         Use of torches and heat guns, and sanding, scraping, and grinding lead-based paint sur­faces during remodeling or abating lead-based paint.

·         Maintaining process equipment or exhaust duct work.

Worker protection program

Your employer must develop and implement a worker protection program. The program is essential in minimizing your risk of lead exposure. Some projects involve limited exposure, such as the removal of paint from a few interior residential doors. Others may involve the removal, or stripping off, of substantial quantities of lead-based paints on large bridges.

Engineering controls and good work practices are the most effective way to minimize expo­sure. Respirators cannot be used instead of engineering and work practices but must be used in conjunction with them to control employee exposures.

Lock-Out / Tag-Out

 

If you are required to repair or maintain any machinery or equipment, or any electrical power source, start the job by locking out and tagging out all energy sources and starting mechanisms.  Locking or tagging out is the only sure way to prevent other employees from accidentally activating the system. 

 

Contact your supervisor when tagging out any piece of equipment or machinery so that he is aware of the situation.  Schedule any maintenance or repairs ahead of time with the supervisor to avoid conflicts and any interruptions the work. 

 

Install your tag out or lock out at the power or ignition source.  If a piece of equipment can be activated from more than one location, then additional locks or tags may be required.  Make sure that the tag or lock is secure and will not blow off or fall off the machine. 

 

Machines can still be harmful even when they are turned off.  Make sure that the machine is not coasting to a stop and watch for moving parts that turn by gravity.  Be careful of air or hydraulic pressure lines that have not been bled.  Read the manufacturers recommendations for repairs to avoid any hidden dangers such as springs that are under a load that might accidentally be released. 

 

Remember to remove your lock and tags after your work is complete.  NEVER remove a lock or tag that has been installed by someone else.  If you find a lock or tag out, contact the person who tagged that equipment out and the supervisor for further instructions.  NEVER ASSUME THAT SOMEONE JUST FORGOT TO REMOVE THE LOCK OR TAG. 

 

BE SMART - LARGE JOB OR SMALL, TAG IT OUT FIRST!
