Confined Space Rescue Level I

Technical ReferencesOSHA

Federal Occupational Safety and Health Act of 1970 resulted in regulations imposed on employers to comply with safety and health standards. This act was promulgated by the U.S Department of Labor and gives OSHA the authority to: Investigate Issue citations / safety orders Levy penalties / fines Seek criminal prosecution

Confined Space Rescue Level I

Technical ReferencesOSHA

OSHA guidelines are the framework for NFPA 1006, 1670 and should be utilized as a guideline.

Rescue agencies are not immune from OSHA sanctions and or penalties.

Violation of recommended guidelines per OSHA, NFPA and NIOSH could result in findings of malfeasance / negligence.

Technical References OSHA training requirements in relation to rescue

agencies Agencies must be made aware of confined space

hazards Agencies must receive access to comparable permit

spaces in order to: Develop rescue plans Practice Rescues

Goals Familiarize agencies with potential confined space

environments in jurisdictionConfined Space Rescue Level I

Technical References OSHA requirements for Companies with

confined spaces Identify potential areas for confined space

rescue Apply for and post permits at the confined

space sites Prohibit entry of employees into confined

space areas unless a permit is posted at the entrance and OSHA precautions have been followed.

Confined Space Rescue Level I

Technical ReferencesOSHA General Employer Requirements

All permit spaces must have danger signs, or other effective means, to designate confined spaces in the workplace

Employers who determine that employees will not enter permit space must still take effective measures to prevent employees from entering the space

Confined Space Rescue Level I

Technical ReferencesOSHA General Employer Requirements

Employers whose employees enter a permit space are required to have a written permit-required confined space program

Employees must identify and evaluate permit space hazards before making entry

Develop and implement procedures/operations/practices directed at safe entry operations Specify acceptable entry conditions Isolate permit space Control atmospheric hazards Establish barriers Verify acceptable conditions throughout the duration of any

authorized entry.

NFPA Rating Summary Health (Blue)

4 Danger May be fatal on short exposure. Specialized protective equipment required

3 Warning Corrosive or toxic. Avoid skin contact or inhalation 2 Warning May be harmful if inhaled or absorbed 1 Caution May be irritating 0 No unusual hazard

Flammability (Red) 4 Danger Flammable gas or extremely flammable liquid 3 Warning Flammable liquid flash point below 100° F 2 Caution Combustible liquid flash point of 100° to 200° F 1 Combustible if heated 0 Not combustible

Reactivity (Yellow) 4 Danger Explosive material at room temperature 3 Danger May be explosive if shocked, heated under confinement or mixed

Technical References Lethal Dose is expressed as LD50

Single dose that will cause death of 50% of a group of test animals exposed to it by any route other than inhalation

Lethal Concentration is expressed as LC50 Median lethal concentration of a hazardous

material which is the concentration of a material in air that on the basis of laboratory tests (inhalation) is expected to kill 50 % of a group of test animals when administered in a specific time period

Confined Space Rescue Level I

Technical References Detection of flammable or toxic

atmospheres. Acceptable levels after ventilation are defined

as 50% of the level of toxic or flammable substance that would constitute a hazardous atmosphere.

Methane 0.5% is considered hazardous, therefore 0.25%

would be the acceptable maximum level. Chlorine

0.5 PPM is considered hazardous, therefore 0.25 PPM would be the acceptable maximum level.
