. Pass a fit-test with each type of respirator you may  use. . Be trained to use the respirator(s). Checking Facepiece Seals Complete   the   following   seal   checks   on   the facepiece when you first put on a respirator: POSITIVE  PRESSURE  CHECK.–  Place your palm or thumb over the exhalation valve and press lightly.  Exhale  gently.  The  respirator  is  properly  sealed if no air leaks around the edges and you feel a slight positive pressure inside the facepiece. NEGATIVE PRESSURE CHECK.-  Place your palm(s) over the cartridge(s) or canister inlet. Inhale gently. The respirator is properly sealed if no air leaks around the edges and you feel a slight negative pressure inside the facepiece as it collapses slightly towards the face. Inspecting Respirators Inspect all respirators routinely before and after use. Inspect emergency use respirators after each use and at least monthly. Inspect SCBAs before and after each use and at least monthly. In all inspections, look for any defects in fit; seal; material; filter, cartridge, or canister selection; cleanliness; and function. THE HAZARDOUS MATERIAL/WASTE PROGRAM Navy  ships  require  hazardous  material  (HM), therefore they produce hazardous waste (HW). The hazardous material/waste program was developed to manage both HM and HW. This chapter will cover the general  requirements  for  HM  and  HW,  both  of  which are a chain of command responsibility that begins with the  individual  sailor  and  extends  to  the  commanding officer. PROGRAM ELEMENTS The following elements are needed to carry out an effective  HM/HW  program: l  Designate  adequate  storage  for  HM/HW. l Control purchasing, receipt, and issue to avoid accumulation of excess HM. .  Follow  approved  safety  standards  for  the  use  of HM. l l l l Collect, segregate, and dispose of HW. Respond   to   HW   emergencies. Obtain material safety data sheets (MSDSs) for onboard  HM. Train personnel as necessary. HAZARDOUS MATERIAL HM is any material that, because of its quantity, concentration,  or  physical  or  chemical  characteristics, may pose a substantial hazard to human health or the environment   when   purposefully   released   or accidentally   spilled.   The   most   common   HM   are flammable/combustible   materials,   toxic   materials, corrosive  material  (including  acids  and  bases), oxidizing  materials,  aerosol  containers,  and  compressed gases. There are other HM that we will not cover in this manual because the engineering department is seldom involved with them. They are ammunition, weapons, explosives,  explosive-actuated  devices,  propellants, pyrotechnics,  chemical  and  biological  warfare materials,   medical   and   pharmaceutical   supplies, medical waste and infectious materials, bulk fuels, and radioactive  materials. HAZARDOUS WASTE HW is any discarded material (liquid, solid, or gas) that  meets  the  definition  of  HM  and/or  is  designated  as a hazardous waste by the EPA or state authority. The term hazardous material turned into store  (HMTIS) refers to usable HM in excess of a ship’s needs and awaiting transfer to a shore activity. The term hazardous material  turned  into  disposal  (HMTID)   refers   to nonusable HM awaiting transfer to a shore activity for disposal. MATERIAL SAFETY DATA SHEETS MSDS   are   technical   bulletins   that   contain information  about  material  such  as  composition, chemical and physical characteristics, health and safety hazards, and precautions for safe handling and use. MSDSs are required for every HM and they must be readily available to personnel who use or handle HM. The Naval Safety Center assigns numbers to all MSDSs used by forces afloat. MSDS numbered stickers are provided to help correlate the MSDS to the product label for ready reference, recognition of hazardous material, and training. All personnel using HM must be trained to 10-11
