SCBA Systems & the Dangers of Confined Spaces

USA Made
SCBAs are often used in confined spaces or in atmospheres that are immediately dangerous to life and health (IDLH).
Lower-priced, high-quality, comfortable SCBA provides reliable protection against hazardous environments
• Open-circuit, positive-pressure SCBA
• Minimal moving parts decreases maintenance
  costs and makes model more durable
• Low profile design and light weight of the
  mask-mounted regulator minimizes fatigue,
  provides unobstructed vision and decreases
  the chance of damage
• Exclusive Air Klic fastening system assures quick,
  secure installation of the regulator in facepiece
• Silicone facepiece is extremely durable and
  comfortable in hot or cold environments
• Weighs 22 lbs. and has a 30-minute cylinder
• Lens has a chemical-resistant, hard anti-scratch
  coating on the outside and anti-fog coating
  on the inside
• NIOSH Approval #TC-13F-285
Know the Dangers of Confined Spaces
What is a confined space?
A confined space is defined as an area that:
• is large enough for a person to occupy
• is difficult to get in and out of
• is designed for only short-term work
Confined spaces can be found in many places of ag or horticultural operations, such as:
• Silos, grain bins and manure pits              • Cold storage rooms
• Well shafts and deep trenches                  • Hopper rail cars and tank trucks
• Agricultural chemical tanks
Why confined spaces are dangerous
Unlike other hazards ag/hort workers are faced with, the concern with a confined space is not an injury that a worker can recover from, but a fatality. Confined spaces contain hazards that will not only injure a worker, but will often
take his or her life. This is why precautionary measures such as gas monitoring and ventilating the
space should be taken.
More specifically, confined spaces are dangerous because:
• Certain gases such as methane may be produced in confined spaces.
These gases displace oxygen in the air you breathe.
• Cold storage rooms often have the oxygen pumped out of them to help preserve foods.
• Gases such as carbon monoxide, methane and hydrogen sulfide may build up to toxic levels.
• Some of these gases are odorless, so you won't even know they are there.
• The buildup of these gases can easily be ignited, causing a fire or an explosion.
• Confined spaces also have many physical hazards. These include falling objects,
  wet surfaces, sloping sides and loose material that can break under your weight.
Protecting you and your workers
Some steps you should take in protecting yourselves and others in confined spaces are to:
Determine what harmful contaminants are present in the confined space. Many confined
spaces have multiple harmful gases.
• Monitor the space for harmful gases and vapors before you decide to go in.
• If harmful gases are present, ventilate the space, then monitor again.
• Monitor continuously any time someone is in the confined space.
• Always wear the appropriate personal protective equipment.
• Always turn off, tag and "lockout" any energy sources such as augers or mixing blades so
  that no one can restart the equipment and injure a worker in the space.
• Have appropriate rescue procedures in place should something go wrong.
• Have workers who enter the space wear a full-body harness and lifeline so he or she can
  be easily rescued from the space without another person having to enter and risk injury.
• If a rescuer does have to enter, make sure he or she has appropriate respiratory protection
  like a SCBA (self-contained breathing apparatus).
• Have an attendant outside any time someone has entered the space.
