HMUG PPE Tip 002



Each HMUG Group is further broken down and contains the following sections:


a. General Information - The information found in this section provides examples of materials which

fall into the group, and provides informational notes specific to certain materials in the group. Also provided is a brief discussion in reference to material hazards associated with the HMUG group (i.e., whether a material exhibits a fire hazard, is a reactive material, or is a toxic material).


b. Risk Assessment - The Risk Assessment section provides information that should be considered when assessing the risks associated with the handling or use of the material, or when conducting Operational Risk Management (ORM) in preparation for planned use or handling of the material.


c. Compatibility and Storage Information - The Compatibility and Storage Information section lists examples of materials that are not compatible with the specified HM group, and provides required storage information for the HM. Also included is general guidance regarding adverse reactions that can be expected if materials from incompatible groups are mixed together. The speed, strength, and duration of the reaction are determined by the exact chemicals which become mixed and the quantities involved


d. Control Measures/Personal Protective Equipment (PPE) - Control Measures/PPE. The Control Measures/PPE section identifies and prescribes general PPE that is appropriate for the chemical hazards in the group. PPE should always be chosen based on the specific materials being used, the operation, process, or maintenance task being performed, and the exposure assessment results. The safety officer, Respiratory Protection Program Manager (RPPM) and medical department representative have access to the detailed Industrial Hygiene (IH) Survey to aid in selecting the correct protective equipment.


e. Safety Precautions - The Safety Precautions section provides safety guidance for using and storing

the HM in the group.


f. First Aid Measures - The First Aid Measures section points out common symptoms and effects of exposure to the HM in the group and provides first aid measures in response to the exposure.


g. Spill Controls - The Spill Control section provides guidance for responding to a spill and guidelines for proper disposal of materials used during spill remediation.


h. Off-load Guidelines - With the establishment of HAZMINCENs ashore and afloat, efforts to reduce hazardous waste, and the tightening of rules concerning HM off-load, the decisions on the off-load of used and excess HM are normally determined by HAZMINCEN personnel in conjunction with the requirements of the receiving shore facility.
