WARNING
Confined Space Hazard
Follow all requirements for confined space when
servicing. All large water bodies and vessels that can be
entered are to be considered permit-required confined
space as defined by the Occupational Safety and Health
Administration (OSHA). The following information is from
OSHA 3138-01R 2004. The full document can be
obtained from www.osha.gov.
Many workplaces contain spaces that are considered to
be “confined” because their configurations hinder the
activities of employees who must enter into, work in, or
exit from them. In many instances, employees who work
in confined spaces also face increased risk of exposure
to serious physical injury from hazards such as
entrapment, engulfment, and hazardous atmospheric
conditions. Confinement itself may pose entrapment
hazards, and working in confined spaces may keep
employees closer to hazards such as machinery
components than they would be otherwise. For example,
confinement, limited access, and restricted airflow can
result in hazardous conditions that would not normally
arise in an open workplace.
The terms “permit-required confined space” and “permit
space” refer to spaces that meet OSHA’s definition of a
“confined space” and contain health or safety hazards.
For this reason, OSHA requires workers to have a permit
to enter these spaces.
By definition, a confined space:
• Is large enough for an employee to enter fully and
perform assigned work.
• Is not designed for continuous occupancy by the
employee.
• Has a limited or restricted means of entry or exit.
These spaces may include underground vaults, bodies,
storage bins, pits and diked areas, vessels, and silos.
• Sewer lines often contain poisonous or
explosive gas such as methane. NEVER enter
or bend over a sewer without proper
ventilation and personal protective
equipment. If another person needs help in a
sewer, immediately call for emergency
assistance. NEVER enter the sewer to help
unless you have been trained to do so and
have proper personal protective equipment.
• NEVER smoke in or around sewer lines,
drains, or catch basins.
• Failure to follow these instructions may result
in death or serious injury.
