Why is this Important? Failure to RECOGNIZE, EVALUATE and CONTROL the hazards associated with confined space entry can result in serous injury or death.

What is a Confined Space? A confined space is recognized as a space which: Is large enough and so configured that an employee can bodily enter and perform assigned work; Has limited or restricted means for entry or exit; and Is not designed for continuous employee occupancy. Confined spaces may also exhibit one or more of the following characteristics: Contain or potentially contain a hazardous atmosphere; or Contain a material which could engulf an entrant; or Have an internal configuration which could trap an entrant; or Presents any other recognized health or safety hazard. It must have all three characteristics to be a confined space (29 CFR 1910.146(b))- MIOSHA Part 90

Basic Principles Confined spaces can be deadly Some confined spaces are more hazardous than others Confined space conditions can change rapidly from no hazards to life-threatening hazards Some confined spaces are so hazardous, a written permit system is required for entry (Permit Required Space) The hazards of confined spaces can often be controlled or eliminated before entering

Hazards of Confined Spaces What are the main hazards of confined spaces? Moving parts Electricity Entrapment Engulfing materials Hazardous atmospheres

Site-Specific Confined Space Process Entry If Eaton employees will perform confined space entry operations, a written, site-specific confined space entry program must be developed. The program must address ALL of the following elements: Local regulatory requirements; Confined space inventory; Site-specific labeling system; Space preparation requirements; Use of entry permit including assignments for completing permit; Atmospheric monitoring; Standby persons; and Rescue procedures Grand Rapids Written specific program can be accessed by all on L:\_MESH\_Public\8.0ProcessSafety\Procedures\Confined Space This process is applicable to Contractors who do access Grand Rapids confined spaces.

Site-Specific Confined Space Process Non-Entry If Eaton employees will NOT enter confined spaces, a written, site-specific confined space entry program shall be developed which must include ALL of the following elements: Local regulatory requirements; Confined space inventory; Site specific labeling system; and Statement that Eaton employees will not enter confined spaces. This Non-Entry applies to Grand Rapids

Permit Required Space When is a confined space so dangerous a written entry permit system is required? When there is an actual or potential “hazardous atmosphere” When the space contains loose material that can engulf a person When the space is configured in a way that can trap a person When there is any other recognized serious safety and health hazard. Employee’s are not permitted to enter a Permit Required Confined Space, unless it can be reclassified as a non-permit required space. Work that requires a permit will be contracted out.

Confined Spaces What is right and wrong with this picture? Description: Associate entering into a confined space in order to conduct work in the space.

Confined Spaces Description: Associate entering into a confined space in order to conduct work in the space. Hazards: No posted visible confined space entry permit. Employees conducting work in area are not able to determine whether or not this is a confined space. No attendant or monitor present outside the confined space during entry. Corrective Actions: Obtain permit for this confined space entry and make obviously visible at this space. Install proper posting of sign to warn employees that this area is a confined space -- ”Permit Required Confined Space -- Do Not Enter”. Have a qualified associate monitor the confined space for the duration of the entry. No warning sign or entry permit posted for Confined Space Entry No attendant or monitor present during entry

No posted confined space permit or warning sign Confined Spaces Description: Photo of an unmanned confined space – underground utility Hazards: No posted visible confined space entry permit or warning sign. Employees conducting work in area are not able to determine whether or not this is a confined space. Corrective Actions: Obtain permit for this confined space entry and make obviously visible at this space. Install proper posting of sign to warn employees that this area is a confined space -- ”Permit Required Confined Space -- Do Not Enter”. No posted confined space permit or warning sign

Confined Space Inventory GR site must maintain an inventory of all confined spaces. The inventory must contain the following information: Identification of the confined space Hazards or evaluation of risk associated with entry into the space Pre-entry atmospheric monitoring requirements

Confined Space Labeling All entrances to confined spaces must be labeled with a weather-resistant sign or label in accordance with applicable legal requirements.

Controlling the Space Most hazards of a confined space can be controlled in the following ways: Prevent employee entry. Post warning signs at the entrance of confined spaces. Remove or reduce hazards in the space first, before a person enters. If hazard cannot be controlled, you must use a written permit system to enter safely.

Controlling/Eliminating the Hazard Lockout Moving Parts De-energize and Lockout/ Tagout electrical parts or wiring Blank or block pipes that supply the hazard into the space Controlling/Eliminating the hazard before entry is the key.

Contractors Contractors with the need to perform work inside of confined spaces must have a written confined space entry program meeting applicable legal requirements. Eaton will provide contractor management with a confined space inventory containing a list of all confined spaces as well as applicable hazards and monitoring requirements. A confined space entry permit must be utilized by contractors entering the confined spaces. The permit must meet local regulatory requirements and must be signed by a contractor employee who is permitted by contractor management to authorize entry into confined spaces.

Things to Remember A Confined Space must have all three; Is large enough that an employee can enter and perform assigned work Has limited or restricted means for entry or exit Is not designed for continuous employee occupancy Confined space conditions can change rapidly from no hazards to life-threatening hazards Employee’s are not permitted to enter a Permit Required Confined Space, unless it can be reclassified. Most hazards of a confined space can be controlled Controlling/Eliminating the hazard before entry is the key Our procedure for Confined Space is L:\_MESH\_Public\8.0 Process Safety\Procedures\Confined Space
