Why do confined spaces kill so many people?
Why do confined spaces kill so many people?
•Confined spaces are deceiving.
• A confined space often appears to be harmless; no danger signs are apparent and the space may have been entered on prior occasions without incident.
•However, a worker cannot assume that conditions have not changed and that the space is safe for entry each time.

“RELIANCE OF MUNICIPAL FIRE DEPARTMENTS FOR CONFINED SPACE RESPONSE”
Information excerpted from, “Confined Space Emergency Response: Assessing Employer and Fire Department Practices,” by Michael P. Wilson, Heather N. Madison & Stephen B. Healy (2012). This study was published in the Journal of Occupational and Environmental Hygiene (Feb 2012) and is available for purchase from Taylor & Francis Online.
“Reliance of Municipal Fire Departments for Confined Space Response”
• A study has been funded by a legal settlement following the deaths of two workers in a confined space incident in California.

“Reliance of Municipal Fire Departments for Confined Space Response”
• Research by the University of California, Berkeley, indicates that employers may be relying too heavily on local fire departments for confined space rescue.

• These findings indicate that local fire departments may not have the resources to provide the specialized training needed for confined space rescue, especially when “response and rescue” times are such critical factors.

• The study includes some very interesting statistics about fire department response times, rescue times, and capabilities. – It also shows that rescue
times increase dramatically when hazardous materials are present.

Municipal Response Statistics
• According to the report, fire department confined space rescue time estimates ranged from 48 to 123 minutes and increased to as much as 173 minutes when hazardous materials were present.

Municipal Response Statistics
• According to the report, “estimates made by fire officers show that a worker who experiences cardiac arrest, deprivation of cerebral oxygen, or some other highly time-critical, life-threatening emergency during a confined space entry will almost certainly die if the employer’s emergency response plan relies solely on the fire department for rescue services.”
Posted on May 22, 2012 by Rescue Talk
Municipal Response Statistics
• Researchers proposed that a more appropriate role for fire departments would be to support a properly trained and equipped on-site rescue team and to provide life support following a rescue.

PEL
• PERMISSIBLE EXPOSURE LIMIT– Ceiling values - at no
time should this exposure limit be exceeded.
– 8-hour Time Weighted Averages (TWA) - an average value of exposure over the course of an 8 hour work shift.
21
STEL
• SHORT-TERM EXPOSURE LIMIT
– The maximum concentration of a chemical to which workers may be exposed continuously for up to 15 minutes (4 times per day) without danger to health or work efficiency and safety.
IDLH
• IMMEDIATELY DANGEROUS to LIFE and HEALTH
– Any condition which poses an immediate threat to the health of life on an entrant, or;
– Would cause irreversible adverse health effects, or;
– Would interfere with an individual’s ability to escape unaided from a permit (confined) space.

IDLH
• IMMEDIATELY DANGEROUS TO LIFE OR HEALTH
– The maximum concentration of gas from which a worker could escape within 30 minutes without experiencing any escape-impairing or irreversible health effects
IDLH
• Under the NIOSH respirator decision logic, "highly reliable" respirators (i.e., the most protective respirators) would be selected for:– Emergency situations – Fire fighting*– Exposure to carcinogens – Entry into oxygen-deficient atmospheres– Entry into atmospheres that contain a substance at a
concentration greater than 2,000 times the NIOSH REL or OSHA PEL
– Entry into immediately dangerous to life or health (IDLH) conditions
* Structural fire fighting is assumed to be an IDLH atmosphere.
IDLH
• These "highly reliable" respirators include either:
– a self-contained breathing apparatus (SCBA) that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode, or

IDLH
• These "highly reliable" respirators include either:
– a supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary SCBA operated in a pressure-demand or other positive-pressure mode.
IDLH
• The purpose for establishing an IDLH value was to determine the airborne concentration from which a worker could escape without injury or irreversible health effects from an IDLH exposure in the event of the failure of respiratory protection equipment.
• In determining IDLH values, NIOSH considered the ability of a worker to escape without loss of life or irreversible health effects along with certain transient effects, such as severe eye or respiratory irritation, disorientation, and incoordination, which could prevent escape.
IDLH
• As a safety margin, IDLH values are based on effects that might occur as a consequence of a 30-minute exposure.
• However, the 30-minute period was NOT meant to imply that workers should stay in the work environment any longer than necessary;
• In fact, EVERY EFFORT SHOULD BE MADE TO EXIT IMMEDIATELY!
24
IDLH
• 1910.134(g)(3) -Procedures for IDLH atmospheres.
– any entry into a confined space with an IDLH atmosphere would require a rescue standby present during the entire entry operation.

• The review board identified five major factors which combined to cause the fire and the astronauts' deaths:
– An ignition source most probably related to exposed electrical wiring and leak-prone plumbing
– Pure oxygen atmosphere at high pressure
– Flammable (combustible) materials in the cabin
– A hatch cover which could not be quickly removed at high pressure
– Inadequate emergency preparedness

Victim Removal
• Can the victim be easily moved towards the opening with current equipment carried by the team?
– Is an additional team needed to make the move?
• Assure as much c-spine control as is possible based on the space and the victims condition.
Victim Removal
• Use removal systems on the exterior which are applicable to the size and weight of the victim.
– Mechanical advantage systems are much preferred over manual hauling.
– Do not use electric winches, et., to remove victims; these allow little control and could result in dismemberment or additional injury.
51
Victim Removal
• Decide if the victim is to be removed head first or feet first.
– Avoid the use of wristlets on patients with burns to the extremities.
Victim Removal
• Assure that if the victim is to be moved through an opening, either vertical or horizontal, that proper procedures should be used for packaging.
• Assure that all team members are stationed to the egress side of the hole/opening in the event the victim becomes lodged. – Always try to avoid being blocked-in by a victim.
Victim Removal
• When the move is made, assure it is made quickly and smoothly, leaving the time the space is blocked for egress as minimal as possible.
• Assure that the exterior personnel as well as interior teams are aware of the move and a plan is agreed upon prior to blocking the space.
52
Victim Removal
• Assure that all air lines and connections are clear of the victim and his movement path to assure that no air line problems develop as a result of the victim becoming entangled or pinching off the lines.
• Once the victim is clear from the space remove all entry team personnel and equipment.
