An average of 92 workers are killed each year in confined space accidents. Magid Glove and Safety teamed up with MSA to create this presentation in effort to help reduce that number by informing you of these hazards and providing you simple solutions to better test your work environment.

 An average of 92 workers
are killed each year in
confined space accidents
 “Rescuers” make up 60% of
confined space fatalities
Confined Space Dangers

5. Because every life has a purpose…© MSA 2012
Confined Space Hazards
 Presence of toxic gases
 Oxygen deficiency or enrichment
 Potential for engulfment
 Flammable gas above 10% LEL
 Mechanical Devices
 Physical Obstacles
 Sloped floors which may pin &
cause asphyxiation
 Any potential for IDLH
atmospheres

6. Because every life has a purpose…© MSA 2012

 Hazardous Atmosphere
• An atmosphere that may pose a
risk of death, incapacitation,
impairment of the ability to self-
rescue, or acute illness.
◘ Flammable gas, vapor or mist >
10% of LEL
◘ Oxygen < 19.5% or > 23.5%
◘ Airborne combustible dust that
meets LFL
◘ Atmospheric concentration of
substance in excess of OSHA
PELs in Subpart G or Z
◘ Any other condition that is
considered IDLH
Key Definitions

7. Because every life has a purpose…© MSA 2012
What is LEL?
 Below Lower
Explosive Limit -
not enough fuel to
ignite
 Above Upper
Explosive Limit -
not enough oxygen
 Between LEL and
UEL -atmosphere is
explosive

Need to sample at all levels in confined space
METHANE
(Lighter Than Air)
CARBON MONOXIDE
(Same Molecular Weight As Air)
HYDROGEN SULFIDE
(Heavier Than Air)
Gases Have Different
“Molecular” Weights

 Initial testing shall be completed
with the ventilation systems shut
down.
 Further testing shall be
conducted with ventilation turned
on
 Conducted in a manner that
represents the atmosphere
throughout the confined space
Atmospheric Testing

10. Because every life has a purpose…© MSA 2012

 Instrument Reliability
Verification
• Calibration shall be
conducted according to the
manufacturer’s
recommendations
• At a minimum, a function
check (e.g., bump test) shall
be done prior to each days
use.
• An instrument maintenance
record shall be maintained.
Calibration and Bump Testing

11. Because every life has a purpose…© MSA 2012
Why use an Automated (GX2) Test System?
• Ease of Use
◘ Fully automated making bump testing and calibration so easy, that anyone
can do it
◘ Electronic cylinder holder allows customers to be up and running with no
setup required
• Proactive Safety
◘ Track bump testing and calibrations for instrument fleet
◘ Download instrument data logs and send automatic emails when action is
required
• Best Total Cost of Ownership
◘ Track gas usage, gas expiration, end of sensor life warnings, sensor
replacements, and instrument history to reduce down-time and overall
maintenance costs
◘ Optimized for use with Xcell sensors yielding fastest test times in the
market!

XCell Sensor
 Designed and built by MSA
• MSA IS Advancing Sensor Technology!
• Our sensors are designed for OUR instruments!
• We have the experts to support YOU!

14. Because every life has a purpose…© MSA 2012
XCell Ex Sensor
 XCell Ex - Catalytic Combustible Sensor
• 4-Year Life, Fast Response, Very Durable
• Only industry sensor with two detector beads (Patent Pending)
◘ Only one bead active at a time – doubles working life of sensor
• Patent-Pending metal alloy support wire for increased
durability
• More poison resistance to silicones and sulfur compounds
• Fast T(90) response time, Typical < 10 sec CH4

15. Because every life has a purpose…© MSA 2012
XCell O2 Sensor
 XCell O2 - Oxygen Sensor
• >4-Year Life, Fast Response, Very Durable
• Long life from patent-pending “Lead Free” sensor design
◘ Nothing is consumed in the chemical reaction
◘ Most other sensors die at 2-years when enough lead is converted
• Fast T(90) response time, Typical < 10 sec O2

16. Because every life has a purpose…© MSA 2012
 MSA provides the best portable instrument solutions!
• Speed of response, advantages of faster alarming
◘ Humans average walking speed = 83m per min
◘ t90 avg response time of big 4
♦ Xcell Sensors = 10-15 sec (~20m into the CS)
♦ Industry avg = 25-30 sec (>40m into the CS)
♦ Action can be taken in half the time in potential life-threatening
situations!
• Best Total Cost of Ownership
◘ Longer Sensor Life
◘ Calibration Gas Flow Rate
 We have the best gas detection instruments in the market!
• Reliable, durable and easy to use
Confined Space: Why
MSA is Simply the Best

Industry first LEL, O2, H2S, CO, SO2 bump and
calibration using a single cylinder
• Bump test time 10 seconds
• Calibration time 60 seconds
Why are we first?
• XCell SO2 sensor T90 response time is
6 times faster than industry average
• Slower SO2 calibration times cause long exposures of
H2S which will kill/poison the LEL sensor
