EM 385-1-1 Paragraph 6-8 (a.–e.).

6-8. General Requirements (a.–e.).

a.  Hazard Evaluation and Control.  Jobsite operations, materials, and equipment involving potential exposure to hazardous or toxic agents or environments must be evaluated by an IH, or equivalent CP in industrial hygiene operations, to identify workplace hazards and plans required for implementation based on potential exposure (see para 6-7). (6-8.a)

(1)  The hazard evaluation must document the workplace and activity evaluated, the nature of the evaluation (air, biological or radiological samples, etc.), any controls and training used, that it serves as certification of hazard evaluation, the name, position, and credentials of the person certifying the evaluation has been performed, and the date of the evaluation. This evaluation must be documented in a written report and available for review by the local SOHO/USACE supervisor/KO or COR.

(2)  For USACE operations, frequency of evaluations will be conducted as required by initial survey determination based on DOEHRS-IH shop priorities.

(3)  Mitigate hazards according to paragraphs 1-6 or 2-6, as applicable.

(4)  In addition, regular housekeeping (work and break area surface cleaning) and personal decontamination procedures must be instituted in areas where operations generate toxic dust and fume hazards.  The frequency of surface cleaning and of decontamination procedures is dependent on the nature of the hazard and frequency and risk from the exposure.  Include housekeeping procedures in the applicable plan. (See para 6-7 and chapter 35)

b.  Exposure Standards.  Occupational exposure, through inhalation, ingestion, skin absorption, or physical contact, to any hazardous or toxic agent more than the OEL is prohibited.  (6-8.b)

(1)  Comply with all applicable standards and regulations to reduce contaminant concentration levels to as low as reasonably achievable.

(2)  For activities where occupational exposure to a chemical or biological warfare agent is possible, comply with current DA SOH requirements for chemical and biological agents such as AR 385-10 chapter 14 Biological Agents, AR 385-10 chapter 21
Chemical Agent Safety Management, and AR 50-6 Chemical Surety.

c.  Labs.  For laboratory use of chemicals follow 29 CFR 1910.1450 (29 CFR 1910 Subpart Z).  (6-8.c)

d.  Testing and Monitoring.  (6-8.d)

(1)  Approved and calibrated testing devices must be provided to measure hazardous or toxic agents and environments.  Devices must be labeled with calibration information (that is, name of individual performing the calibration and date of the most current calibration).  Calibration results must be maintained in a calibration log.  For USACE operations, IH equipment calibration results must be maintained in the DOEHRS-IH.

(2)  Individuals performing testing and monitoring must be trained according to paragraph 6-3.

(3)  Testing and monitoring devices must be used, inspected, and maintained according to the manufacturer's instructions. Maintain a copy of the manufacturer’s instructions with each device.

(4)  Use appropriate NIOSH, OSHA, EPA, or DA sampling and analytical methods, or other independently verified sampling and analytical methods.

(5)  Laboratories used for analysis must be accredited by nationally recognized bodies, such as the AIHA, for the type of analysis performed.

(6)  Determination of the concentration of and hazards from hazardous or toxic agents and environments must be made by a qualified IH or other CP.

(7)  Perform testing and monitoring during initial startup and as frequently as necessary to ensure the safety and health of the workers or other potentially exposed individuals.

(8)  Records of testing/monitoring must be maintained onsite and must be available to the local SOHO/USACE supervisor/KO or COR, upon request.  For USACE
    operations, records of testing/monitoring are to be maintained in DOEHRS-IH.

e.  Hazardous and Toxic Agents Handling.  (6-8.e)

(1)  When engineering and work practice controls or substitution are either infeasible or insufficient, appropriate PPE and chemical hygiene facilities must be provided and used for the handling of hazardous or toxic agents.

(a)  Refer to the SDS to determine PPE requirements.  An IH, Safety, or other CP
        must determine the scope and type of PPE required.

(a-1)  Special attention must be given to selecting proper chemical protection when working with materials designated with a “skin” notation by OEL.  Such materials may produce systemic toxic effects through absorption through unbroken skin.  (See chapter 5)

(a-2)  Before commencing use of epoxy resins, concrete, or other dermatitis- producing substances, employees must be made aware of the manufacturer’s skin protection recommendations.  Barrier cream ointment or other skin protection measures recommended by the manufacturer or the SDS for the specific exposure must be available for use.

(b)  When the eyes or body of any person may be exposed to hazardous or toxic agents and suitable facilities for drenching or flushing of the eyes and body are required, they must comply with ANSI Z358.1.  Such facilities must be provided in the work area for immediate emergency use, no more than 10 seconds from the hazardous or toxic agent.

(b-1)  Emergency eyewash equipment must be provided where there is the potential for an employee’s eyes to be exposed to corrosives, strong irritants, or toxic chemicals.

(b-2)  The emergency eyewash equipment must irrigate and flush both eyes simultaneously while the operator holds the eyes open.

(b-3)  The emergency eyewash equipment must deliver at least 0.4 gal (1.5 L) of water per minute for 15 minutes or more, providing a minimum of 6 gal (22.7 L) of water.

(b-4)  Water used in emergency eyewashes and showers must meet potable water standards. When these items are exposed to the elements, steps will be taken to
            ensure the water does not freeze or become stagnate.

(b-5)  Personal eyewash equipment may be used to supplement emergency washing facilities, they cannot be used as a substitute (see para 6-5.b).

(b-6)  All plumbed emergency facilities and hand-held drench hoses must be connected to an approved potable water supply and activated weekly.

(b-7)  All facilities must be inspected according to paragraph 6-5.b to ensure they function correctly and the quality and quantity of water is satisfactory for emergency washing purposes.

(c)  When personal protective clothing is required, an area must be established for the removal of the personal protective clothing which limits the spread of any chemical waste, dust, or fume, and workers must be trained in the removal of personal protective clothing and equipment to prevent further spread or contamination (see chapter 35).

(2)  Store hazardous or toxic agents so that they are only accessible to authorized personnel and NFPA 400 according to the manufacturer’s recommendations (for example, SDS), 29 CFR 1910 Subpart H and requirements.

(3)  Hazardous material must be segregated into appropriate storage designated for ignitability (flammable substances), corrosivity (acids and bases), reactivity (avoid water, temperature, pressure), and toxicity according to 29 CFR 1910 Subpart Z, 29
    CFR 1915 Subpart Z, and 29 CFR 1926 Subpart Z.

(4)  All hazardous chemicals, materials, substances, and wastes being stored prior to transportation must be under the supervision of a qualified person (see para 6-4.b).

(5)  Transportation, use, and storage of hazardous or toxic agents must be planned and controlled to prevent contamination of people, animals, food, water, equipment, materials, and environment.

(6)  Dispose of surplus or excess hazardous or toxic agents in a manner that will not contaminate or pollute any water supply, ground water, or streams, and that complies with applicable federal, state, and local requirements and guidelines.

(7)  Do not use containers that have held hazardous or toxic agents to hold other materials unless they have been managed or cleaned under hazardous waste and DOT regulatory requirements.

(8)  Every hazardous or toxic agent being transported for disposal must be transported with a copy of the substance's SDS.

(9)  Persons who prepare shipments of hazardous chemicals, materials, substances and/or wastes that are defined as hazardous material under DOT regulations are required to be trained according to paragraph 6-3.f.
