NIOSH “FACE” StudyFor confined space fatal incidents: Locations types include:
31% tanks, 26% vats/pits, and 27% sewers
36% involved multiple victims 79% hazardous atmospheres
• 43% had oxygen deficient atmospheres• 29% had toxic atmospheres• 7% had flammable atmospheres
21% involved physical hazards
Mary Yakawich
here is some of the data:70 incidents, 109 fatalities; 66% May-August; 36% involved multiple victims. Types of incidents: hazardous atmospheres 79% (43% O2 deficient, 29% toxic, 7% flammable), physical hazards 21%. Industries with highest number of incidents: ag/forestry/fishing, construction, manufacturing, public administration. Training procedures, % of incidents: training 67%, written safety procedures 40%, permits 0%, standby 37%, warning posted 7%. Type of training received (% of fatalities): on-the-job safety 41%, confined space 6%, classroom safety 19%, none 34%. Reason for entry (% of fatalities): maintenance 40%, rescue 36% (only 4 victims were emergency responders), inspection 10%. Location (% of fatalities): tanks 31%, vats/pits 26%, sewers 27%]
What is The Definition of a Confined SpaceWAC 296-809-100
A Confined Space
Large enough for the whole body to enter and work, and
Has limited or restricted means for entry or exit, and
Is not designed for continuous employee occupancy
Is a space that is all of the following:
Non-Permit Confined Space
WAC 296-809-20002 Is a confined space that does not
contain actual hazards or potential hazards capable of causing death or serious physical harm.
Hazards found Within Confined Space s
Contains or has a potential to contain a hazardous atmosphere, toxic gases, fumes and vapors
Contains a material with potential for engulfing or causing asphyxiation
Internal configuration that could allow someone entering to be trapped by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section
Contains any physical hazard such electrical or mechanical or any other recognized serious safety and health hazard.
Confined Spaces That You May Be Familiar
With Silos Grain bins Well shafts Chemical tanks Cold storage rooms Hopper rail cars Truck tanks Sewers
Do’s and Don’ts
Evaluate the worksite for confined spaces
Develop a written program Train employees Provide safety equipment Test the atmosphere if necessary
Confined Space Don’ts
Don’t enter unless you have to Don’t enter without a permit Don’t enter without proper PPE Don’t enter without proper training Don’t operate in or around confined
spaces with equipment that could cause sparks
Controlling Hazards In Permit-Required Confined Space
Limit employee access to confined spaces by using entry barriers or locks.
Post warning signs at the entrance of confined spaces.
Make sure that unauthorized workers do not enter the confined space.
Controlling Hazards (cont).
Written program
Complete a permit for each entry
Extensive employee training
Employee assigned duties
Controls (cont.)Drain or pump out liquid contents, if any.
Blank off all in-feeding lines.
Air test and ventilate.
Continue ventilating constantly.
If possible, remove any sludge deteriorate from inside the confined space.
Exit space if conditions change
Entry Permit
Describes each individual’s roles and responsibilities,
Specifies safety equipmentand respiratory protection,
Tells how long the job will take,
States hazards found in the space includes atmospheric monitoring.
TrainingWAC 296-809-400
Before first assigned duty
Before any changes in assigned duty
Whenever there is a change in the PRCS
Any deviations from the PRCS procedures
Inadequacies in employee’s knowledge or use of procedures
