39
WHAT IS A CONFINED SPACE
Restricted openings for entry/exit Ventilation not expected to remove hazardous contaminants May contain or produce hazardous contaminants or oxygen deficiencies or enrichment Not intended for human entry/occupancy on a routine basis
40

43
RESPIRATOR REQUIREMENTS FOR IDLH

44
WHAT ARE GFE TESTING FOR

50
Toxic Materials Enter Body 3 Ways
Ingestion (eating, drinking) Absorption (touching) Inhalation (breathing)
51
Types of air purifying respirators
Mechanical - protection from particles (dust, fumes, fog) | Chemical - vapors and gases in low concentrations
52
types of supplied air respirators
Air-line | Self-Contained Breathing Apparatus (SCBA)
53
IDLH ENTRY
Entry into IDLH spaces is authorized only under emergency conditions. Only the CO can authorize opening and entry into IDLH spaces.
54
IDLH RESPIRATORY 
REQUIREMENTS
Full facepiece, pressure demand self-contained breathing apparatus (Fire Fighting SCBA) Full face piece pressure demand air-line respirator equipped with an auxiliary self-contained air supply having a minimum rated service life of 15 minutes (SAR/SCBA)
55
ADVANTAGES OF SAR W/ SCBA 
OVER SCBA
ADVANTAGES OF SAR W/ SCBA 
OVER SCBA
56
VENTILATION PRIOR TO ENTRY
“There will be a minimum of two air changes prior to entry into a confined space unless installed ventilation is in operation” NSTM 074-21.3
57
TYPES OF VENTILATION
GENERAL LOCAL EXHAUST DILUTION
58
GENERAL VENTILATION
Provides uncontaminated air for breathing or general comfort Supply or Exhaust ONE COMPLETE AIR CHANGE EVERY 3 MINUTES
59
LOCAL EXHAUST VENTILATION
Captures contaminants as they are generated Draws them through exhaust ductwork intake positioned 6-10 inches from work generating contaminantsEffective for welding and solvent cleaning Exhaust only 100 Linear FPM
60
DILUTION VENTILATION
Portable, locally rigged exhaust ventilation Replaces contaminated air with fresh air, diluting concentration Used to control flammable, O2 deficient/enriched areas SAR may be required when toxics are being generated
61
DILUTION VENTILATION VOLUME FORMULA (Welding)
One complete air change every 3 minutes, but not less than: 2,000 cubic feet per minute (ft3 /min) per welder, if a 5/32 inch or 3/16 inch rod is used. 3,500 ft3 /min per welder, if a 1/4 inch rod is used. 4,500 ft3 /min per welder, if a 3/8 inch rod is used.
62
SHORT CIRCUITING
Source of make up air is too close to the exhaust trunk Effective volume ventilated is insufficient Remedy? Place trunk further into space
63
RECIRCULATION OF CONTAMINATED AIR
Exhaust discharge is drawn back into the make-up air | Drawn back into space
64
hot work near INSULATION
Remove Insulation 12 inches from the hot work Area Wet Down Non-Removable Insulation and Cover with Fire Retardant Cloth Station Fire Watch with a Charged 1 1/2” Hose
65
hot work near ammunition or explosives
CO must approve in writing any Hot Work in adjacent spaces No Hot Work in any space containing ammunition Remove ammunition prior to availability or overhaul Apply 5 ft rule for adjacent spaces
66
Which Class of Hot Work ALWAYS requires a Fire Watch
Class I : High Energy Sparks
67
Flammables Must be Moved How Far From Work Site
35 Ft
68
Surface Coatings Should be Cleared Away How Many Inches
4 Inches
69
methods for cleaning tanks
water wash, chemical, butterworthing,steam, biological
70
INERTING
May be used when hot work is required and normal cleaning and gas freeing is impossible ”emergency use only” Not for use with gasoline tanks Totally isolate tank from surrounding spaces including common vents and interconnecting pipingGases used: Co2 (heavier than air) Dry N2 (lighter than air & preferred medium) Maintain <1% o2 concentration Work area outside space shall be certified and maintained as “safe for hot work” Dispose of displaced vapor and inerting medium safely
71
pressing up
``` Emergency use only Fill with water Allow gases to vent Maintain less than 1% oxygen Do not conduct hot work within 12 inches below water level ```
72
STEAM BLANKETING
Emergency-use only Complete same as inerting Monitor temperature of tank wall or boundaries (230 deg max) Start 3 hours prior to hot work
73
What is the preferred medium for inerting?
Dry Nitrogen
74
accuro dreager
measures 100 cubic cm per stroke, to test squeeze and insert unbroken tube in the end for 15 mins
75
five first aid priorites
``` cab's airway breathing circulation control bleeding treat for shock treat for broken bones get casualty to medical ```
76
who makes up the primary rescue team
