Within the OSHA Lockout:Tagout regulation, 1910.147 is this prominent
Definition of an Energy Isolating Device: A mechanical device that physically
prevents the transmission or release of energy, including but not limited to
the following: A manually operated electrical circuit breaker; a disconnect
switch; a manually operated switch by which the conductors of a circuit can be
disconnected from all ungrounded supply conductors and, in addition no pole can
be operated independently; a line valve; a block and any similar device used to
block or isolate energy. Push buttons, selector switches and other control
circuit type devices are not energy isolating devices. This has led to a myriad
of circuit breaker lockout solutions. Factories throughout the United States,
in fact the world, now have a variety of lockout solutions for their single
pole and multi-pole circuit breakers.
Often times electrical equipment being used in a factory operation may suddenly shut down. This may be due to an internal power malfunction, a local power plant problem, a sudden jam in a gear, just to name a few. When this type of unintentional shut down takes place, it is extremely important to insure that the equipment does not suddenly start up again. Such an event may catch employees by surprise and lead to a serious accident. The Sensing Saf-Start device automatically “opens” the circuit once there is a sudden power loss. The circuit will remain “open” as long as the equipment power switch is “on.” Once the power switch is turned “off”, the Sensing Saf-Start device will then close the circuit. At that point, with everyone aware that the equipment can now be safely restarted, the power switch can be turned “on” and normal operation resumed.
In September of 1989, The OSHA Lockout:Tagout Regulation CFR1910.147 went into effect. It clearly stated that equipment being serviced had to be completely shut down and had to be both "Locked Out" and "Tagged Out" (with the tag firmly attached to the lock) clearly identifying the person or persons involved in that servicing operation. Furthermore, to insure the tag could not inadvertently slip off, tear off or somehow be removed from the padlock, both the tag and the device used to attach it to the padlock had to be strong enough to "pull" 50 pounds. And thus, the LockWrap(R) Padlock Label was created. The LockWrap acts as a tag and is wrapped securely around the padlock and cannot be removed.
(c) (5)(i) of Lockout Regulation CFR 1910.147 states that Locks, tags, chains,
wedges, key blocks, adapter pins, self-locking fasteners, or other hardware
shall be provided by the employer for isolating, securing or blocking of
machines or equipment from energy sources. Fuse holders and fuse panels are
types of energy systems that are difficult to lockout. In order to satisfy the
OSHA rule, devices have been devised that “blockout and “latchout” these energy
sources. These devices keeps the electrical energy systems “OPEN” with no way
for electrical energy to be reconnected. However, as there is no latch on these
devices, there not be a padlock to insure that these devices will not be
The OSHA Confined
Space Regulation, CFR1910.146 is designed to prevent accidents to employees
when working in a space where one has limited or restricted access for entry or
exit and while in that area might meet up with liquids, gases or obstacles.
Thus, a person entering a confined space must be fully trained in the hazards
to be faced and must wear the appropriate protective clothing. The area is also
constantly monitored for air quality. Before entering a confined space area,
one has to receive a “Confined Space Permit.” To help the process along, a
series of signs and tags have been created. They contain proper procedures to
follow, Caution and Danger announcements as well as directions for those both
entering the area or assisting in the operation.
A smoke-free workplace has many advantages. It reduces the amount of smoking by employees. It
also protects others from the dangers of second-hand smoke. Furthermore,
for the employer, it significantly reduces health care costs. People exposed to
smoke in the workplace are 17% more likely to develop lung cancer.
not have any regulations that apply directly to smoking in the workplace.
However OSHA does have standards which limit the exposure levels of a number of
chemicals. And many of the chemicals are found in tobacco smoke. They include but are not limited to limits on carbon
monoxide, nicotine, sulfur dioxide, ammonia, nitric oxide, formaldehyde and
arsenic. So essentially these require that is no smoking or very limited smoking take
place in the workplace. In addition, employers do have a legal right to both
restrict and also prohibit completely the use of tobacco. In some cases, of course, especially when flammable materials or hazardous machinery is present, it is imperative that smoking be prohibited.
To ensure regulations are followed and
workplace safety improved, a number of workplace signs have been created.
For example where chemicals are used the following
essential signs should be posted: DANGER, OXYGEN, NO SMOKING, NO OPEN FLAMES; DANGER,
BENZENE, CANCER HAZARD, FLAMMABLE – NO SMOKING, AUTHORIZED PERSONNEL ONLY.
In areas where
lead is present: WARNING, LEAD WORK
AREA, POISON!! NO SMOKING OR EATING. That sign may also include a skeleton
When smoking is allowed in some places, a sign may announce: NO SMOKING
EXCEPT IN DESIGNATED AREAS.
Or some prefer low-key signs, such as: THANK YOU FOR NOT SMOKING. Those signs may include
the standard symbol of a cigarette within a circle with a diagonal red line
going through it.
In work areas
populated by multilingual employees the sign may be in more than one language.
An example of that kind of sign might state: NO SMOKING, NO FUMAR.
Signs may be constructed of durable vinyl, with pressure-sensitive backing (for adhering to walls or doors), tough rigid plastic, or the most durable of all, anodized aluminum signs.
industrial zones and factories, employers are required by law to establish and
implement a lockout/tagout program as mandated by OSHA. Workers performing
service or maintenance on machinery and equipment may be exposed to injuries
from the unexpected energy start up of the machinery or equipment, or release
of stored energy in the equipment. The purpose of this program is to raise
awareness of workplace safety and prevent accidents and injuries from occurring
on the job.
