I. Background. A listing of contaminants and a discussion of the safety and health implications of each.

II. Site Location

A. Perimeter determination

B. Marking of the perimeter

C. Existing geographic features, public utilities, and/or private improvements

D. Security measures to preclude unauthorized entry

E. A clearly defined means of egress from the site.

F. A clearly defined primary and backup route to the nearest hospital or route to a backup hospital.

III. Site Layout

A. Determination of contaminated zones

1 .Exclusion Zone (contaminated)

(a) Area A

(i) Where atmospheres may be IDLH

(ii) Known atmospheres containing concentrations capable of being absorbed through the skin or eyes in toxic quantities

(b) Area B

(1) Where atmospheric concentration of contaminant is known and the concentration of contaminants is greater than the protection factor for air purifying respirators

(2) Oxygen deficient or oxygen enriched atmospheres

(3) Skin absorbed contaminants are not present

(4) Safeguards preclude splashing of individuals

(c) Area C

(1) Air contaminant levels do not exceed the protection factors of air-purifying respirators

(2) The contaminant is not a known skin absorber

(3) A reliable history of prior entry exists without acute or chronic effects on personnel

(d) Area D

(1) No known airborne health hazards present

(2) This is the minimum protection area inside the exclusion zone

2. Contamination Reduction Zone. Provides area to prevent transfer of contaminants from the Exclusion Zone to the Clean Zone

3. Clean Zone. The outer area, considered to be clear of contamination

B. Location of support facilities, criteria for selection/

(1) Compatibility with existing prevalent wind directions and associated factors

(2) Ability to remove decontaminated material

(3) Ability to limit contamination spread

C. Methods and procedures for the prevention of contamination spread

D. Access to existing roadways and any associated problems with access and egress to the site

IV. Personnel Protection

A. Determination of PPE for each contaminated zone and area

B. Establishment of medical requirements and methods of implementation

C. An evaluation by the OHP of employees' ability to wear PPE

D. A written PPE document

E. Training specific to each piece of PPE

F. Instruction on proper cleaning, repair, and storage of equipment

G. Procedures for equipment decontamination

H. Proper fitting and limitations

V. Contaminant Monitoring (airborne)

A. Personnel monitoring

B. Area monitoring

VI. Decontamination

A. Personnel decontamination procedures

B. Equipment decontamination procedures

C. Scrap decontamination procedures

(1) Scrap means expendable materials used in the mitigation and/or evaluation process, such as disposable containers, clothing and plastic sheeting

VII. Communications

A. Communications on site compatible with protective equipment used

B. Communications with on call emergency equipment

VIII. Emergency Procedures

A. Chemical exposure

B. Personal injury

C. Potential or actual fire or explosion

D. Environmental accident

E. Radiation

IX. Training

A. Training plan including refresher training for government employees

B. Training requirements for contractor personnel
