Why Comply????

Confined space entry is a leading cause of occupational fatalities in this country.

4

Statistics

The Standard covers 240,000 workplaces and 12.2 million workers

Workers make 4.8 million entries/year Standard may prevent 85% of fatalities

and nearly 11,000 injuries

5

Definition of a Confined Space

Limited means of egress

Can be bodily entered

Not designed for continuous occupancy

6

Definition of Permit-RequiredConfined Spaces

Contains or has potential to contain a hazardous atmosphere

Contains the potential for engulfment Internal configuration that can trap or

asphyxiate entrant Any other serious safety or health hazards

7

Spaces in Schools That Could be Permit-Required

Steam pipe tunnel Boilers & Tanks Sewage pump pit Water valve pit Below grade vaults HVAC air-mixer Air plenums Sawdust collector Water tower Pits for bus repair

8

Typical Non-Permit-Required Spaces

Utility / perimeter tunnels Below-grade trenches Ventilated storage vaults

9

Potential Confined Space Hazards

Engulfment Oxygen deficiency (19.5% or less) Oxygen enrichment (23.5% or higher) Flammable gases or vapors Combustible dusts Toxic substances IDLH atmospheres Physical hazards

10

Atmospheric Testing

Hazards must be tested in this order:•Oxygen content•Combustibility/flammability•Toxic atmospheres

Entrants must be allowed to observe monitoring

11

Reasons for Space Ventilation

Maintain oxygen levels above 19.5%

Maintain toxic gases and vapors at acceptable levels

12

Types of Personal Protective Equipment

Harnesses Retrieval lines Chemical protective

clothing Welding apron/sleeves Respirators Gloves Safety glasses

13

Safety Program Manager’s Responsibilities

Formulate and manage the confined space entry (CSE) program

Maintain a CSE inventory Maintain a list of “Authorized Personnel” Maintain copies of CSE permits Direct the CSE training program Maintain CSE rescue equipment Coordinate contractor activities in confined

spaces on school district property.

14

Supervisor Responsibilities

Conduct a pre-entry briefing Ensure that personnel are evacuated

when necessary Ensure that permits are complete and

removed when work is finished Ensure that all necessary equipment

is returned to its proper location Oversee all necessary confined

space activities

15

Attendant Responsibilities

Attend pre-entry briefing Know the hazards of the space Control access to the space Maintain communication with entrants Not to enter the space for rescue Summon emergency services Assist rescue efforts from outside the space

16

Attendant Responsibilities (cont.)

Remain at the site while entrants are inside

Order a space evacuation when conditions warrant such an action

Maintain an accurate count of the number of entrants

17

Entrant Responsibilities

Attend the pre-entry briefing Know the hazards of the space Use appropriate equipment properly Exit the space if:

•An alarm is activated•Communication is lost•Unknown exposures are encountered•Ordered to do so

18

Authorized Person Responsibilities

Familiarize themselves with characteristics of spaces

Verify that all hazards and sources of energy have been controlled in the space

Ensure that confined space permit is posted Rescind any permit for noncompliance with

permit requirements

19

Rescuer Responsibilities

Understand the hazards of the space Have current first aid and CPR training Understand appropriate entry procedures Know how to use rescue equipment Practice confined space rescues at least

annually

5. True or False5. If a chemical storage tank is empty, it would not be considered a

confined space. True or False

21

Quiz (cont.)

Quiz Answers

1. A confined space is defined as having limited egress, can be bodily entered, and is not designed for continuous occupancy.

2. False. Some confined spaces may be classified as non-permit-required.

3. The three hazards that must be tested for in a confined space are oxygen content, combustibility and flammability, and toxic atmospheres.

4. False. Entrants must be familiar with all hazards prior to entering a confined space.

5. False. Just because it is empty does not preclude its being defined as a confined space.

23

Quiz Answers (cont.)

6. Examples of typical non-permit-required confined spaces are utility closets, below-grade trenches, storage vaults, and utility sub-basements.

7. True. Confined space entry is routinely one of the leading causes of occupational fatalities.

8. Annual emergency drills are required by the WISHA Confined Space Standard.

9. False. An attendant should never enter a confined space to rescue unless someone else is available to fill the duties as attendant.

10. An entrant should exit a confined space if ordered to do so, unknown exposures are encountered, communication is lost, or an alarm is sounded.
