PREVIEW OF
CONFINED SPACERESCUE AWARENESS
POWERPOINT TRAINING PRESENTATION
TYPICAL REASONS TO ENTER A CONFINED SPACE
Cleaning to remover sludge or other waste materialsInspection of physical integrity & process equipmentMaintenance, removal or application of surface
coatingsTesting of contents & pipingRepairs including welding
TYPICAL REASONS TO ENTER A CONFINED SPACE
Adjusting or aligning internal devices or componentsChecking & reading internal instrumentsInstalling or repair of electrical, communication,
or other cablesRescue of workers injured or over come
DEFINITIONPermit Required Confined Space
Has at least one of the following characteristicsContains or has the potential to contain a hazardous atmosphereContains a material that has the potential to engulf an entrantHas an internal configuration such that an entrant could be trapped or asphyxiatedContains any other recognized serious safety and health hazard
Per Bureau of Labor Statics there are about 92 Confined Spaces
deaths per year60% of all deaths in confined space
rescues are rescuersINCLUDING FIREFIGHTERS
CausesLack of training Improper equipmentNo communications No procedures
SAFETY NOTE
Rescuers should consider all confined spaces as having oxygen-deficiency, flammable, and toxic atmospheres until determined otherwise
CAUSES OF DEATH
65% atmospheric13% engulfment7% struck by falling object6% heat stress or exposure4% others
AWARENESS LEVEL FUNCTIONS
Performs a non-entry retrievalImplements the emergency response system for
confined space emergenciesImplements site control & scene management
REGULATORY/STANDARDS
OSHA 1910.146NFPA 1670ANSINIOSH
STORAGE TANKS
DANGERS IN CONFINED SPACES
Oxygen deficientBy-products of previously stored material
ResidueAbsorbed into tank walls
Accidental leaks or spillsVapor releaseSlip, trip, or fall hazard
ATMOSPHERIC HAZARDS
Atmospheric oxygen below 19.5% (oxygen deficiency)or above 23.5% (oxygen enriched)Flammable gas, vapor, or mist in excess of 10%
of LELAtmospheric concentration of any toxic contaminant above the OSHA PEL
COMMON GASES
Carbon Monoxide Hydrogen sulfideSulfur dioxide AmmoniaMethane Carbon dioxideOxygenAtmospheric hazards reduced below “flammable levels” may still be toxic
MECHANICAL
“Of or relating to machinery or tools”Equipment
Grinding Agitators Mulching DriveshaftsGears Mixers RamsPresses
May have unguarded componentsPowered by Gas/Diesel Pneumatic Hydraulic Electric Steam Heat (fire) Gravity
CAUSES OF PSYCHOLOGICAL HAZARDS
Biological- being physically fit reduces sodium lactate(an anxiety attack chemical)Psychological
Subconscious forcesPersonality disorders, abnormal behaviors
Control TechniquesRecognitionTrainingPsychological control techniques
OSHA REQUIRES
Testing of stratified atmospheres 4‘ in each direction of travel, & each sideSampling probe should be slow to accommodate detector responsesHand held monitors can be attached to rescuers
harness
ENTRY PERMITS
Permit must be approved prior to entryUpon completion of entry it must be signed &
cancelled by entry supervisorMust be retained on file for at least one year
PERSONAL PROTECTIVE EQUIPMENT
Head Eye & faceFoot Hearing Elbow & knee HandBodyRespiratory protectionThe situation, hazards, &
atmospheric conditions dictate the PPE used
HEARING PROTECTION
SPACE ISOLATIONLOCKOUT-TAGOUT
Procedures must be in place to isolate potential energy sources to the space including
Electricity HydraulicSteam Drive
mechanismsPneumatic Gravity flowPressure MomentumStored energy
OSHA DEFINITION
Hazardous energy controlA program of a energy control procedure &
employee training to ensure that before any person performs any service or maintenance on a machine or equipment
they shall be isolated & rendered inoperable
OSHA 6 STEP PROCEDURE
Prepare for shutdownShutdown the equipmentIsolate the equipmentApply lockout/tagout or block/bleed devicesControl stored energyVerify equipment isolationMust be performed by an “authorized” employee only

NON-ENTRY RESCUE
Is conducted without entry to the confined spaceThis can be accomplished with a rope winch
RAPID INTERVENTION TEAM
Provides safety back upDressed the in the same as the entry teamMust be ready to enterCan not be assigned other tasks during rescue
(entry) phaseShould be staged as close as possible to entry
point
HOST EMPLOYER MUST
Inform rescuers of hazards they may encounterProvide rescuers with access to ALL confined
spacesProvide liaison with rescuersProvide any technical assistance necessary
