what inventor was killed while fixing his crushing machine?
Stephen B. Ackers
OSHA code for the control of hazardous energy - lockout tagout
- 1910.147
- has specific procedures on how to lockout/tagout every piece of equipment
what is hazardous energy?
all machines and equipment use or manipulate energy to perform work. that energy may be electrical, mechanical, hydraulic, pneumatic, chemical, or thermal. that energy may be stored (such as in springs, steam, or pressurized air or liquids), even after the equipment has been shut off
what does the control of hazardous energy sources (lockout-tagout) standard cover? (1910.147)
the standard for the control of hazardous energy sources (lockout-tagout) covers servicing and maintenance of machines and equipment in which the unexpected energization or startup of the machines or equipment or release of stored energy could cause energy to employees
why is there a standard? (again, 1910.147)
- who faces greatest risk?
- what kind of injuries does this include?
- average lost time for injuries?
- about 3 million workers actually servicing equipment face the greatest risk. these include craft workers, machine operators, and laborers (typical injuries include fractures, lacerations, contusions, amputations, and puncture wounds with the average lost time for injuries running 24 days
OSHA estimates that compliance with the standard will prevent how many fatalities/serious injuries/minor injuries?
- 120 fatalities each year
- 28,000 serious injuries each year
- 32,000 minor injuries each year
under this ruling, how many general industry workers will be protected from accidents under this ruling?
about 39 million general industry workers
how do most companies punish people for lockout/tagout violations?
most companies do NOT use progressive discipline, but rather the usually skip steps (straight to fire, or other severe punishment)
what does lockout/tagout mean?
lockout/tagout means deenergizing or controlling all energy sources and physically locking all power sources (i.e., circuit breakers, switches, valves, etc.) in the “OFF” (deenergized) position
lockout/tagout is the ____ most regulation violated in 2014
5th most
what is the purpose of lockout/tagout?
the purpose of lockout/tagout is to prevent the accidental release of stored energy by locking all energy sources in the “OFF” or deenergized position
what is the scope of the lockout/tagout standard?
this standard covers the servicing and maintenance of machines and equipment in which the “unexpected” energization or startup of the machines or equipment, or release of stored energy could cause injury to employees
this lockout/tagout standard does NOT cover:
- construction and agriculture employment
- employment covered by parts 1915, 1917, and 1918 (maritime)
- installations under the exclusive control of electric utilities for the purpose of power generation, transmission and distribution, including related equipment for communication or metering
- exposure to electrical hazards from work on, near, or with conductors or equipment in electric-utilization installations, covered by Subpart S, and
- oil and gas well drilling servicing
are normal production operations covered by this standard?
- no they are not.
- servicing and/or maintenance which takes place during normal production operations are covered by this standard only if:
- an employee is required to remove or bypass a guard or other safety device, or
- an employee is required to place any part of his or her body into an area on a machine or piece of equipment where work is actually performed upon the material being processed (point of operation)
whats an exception to the application of this standard?, and why does Sesek refute this exception?
- minor tool changes and adjustments, and any other minor servicing activities, which take place during normal production operations, are not covered by this standard if they are routine, repetitive, and integral to the use of the equipment for production, provided that the work is performed using alternative measures which provide effective protection
- Sesek refutes this exception b/c just because a company thinks what they’re doing is repetitive/routine/normal, doesn’t mean that its actually normal routine work (unsafely having to fix a machine on a regular normal basis doesn’t mean you’re excluded)
this standard does not apply to the following:
- work on cord and plug connected electric equipment for which exposure to the hazards of unexpected energization or startup of the equipment is controlled by the unplugging of the equipment from the energy source and by the plug being under the exclusive control of the employee performing the servicing or maintenance
- hot tap operations involving transmission and distribution systems for substances such as gas, steam, water, or petroleum products when they are performed on pressurized pipelines, provided that the employer demonstrates that:
- continuity of service is essential
- shutdown of the system is impractical
- documented procedures are followed, and special equipment is used which will provide proven effective protection for employees
definition of affected employee
an employee whose job requires him/her to operate or use a machine or equipment on which servicing or maintenance is being performed under lockout or tagout, or whose job requires him/her to work in an area in which such servicing or maintenance is being performed
definition of authorized employee
a person who lock out or tags out machines or equipment in order to perform servicing or maintenance on that machine or equipment. an affected employee becomes an authorized employee when that employees duties include performing servicing or maintenance covered under this section
definition of energized
connected to an energy source or containing residual or stored energy
