residuals  behind  that  must  eventually  be  deposited  in a controlled sanitary landfill facility. At all levels of society, we must take appropriate action   to   abate   pollution   and   to   preserve   the environment   by   properly   disposing   of   solid   waste material. Since all Navy facilities must conform to the laws and   regulations   of   federal,   state,   and   local environmental  agencies,  the  Navy  has  produced  its own   instruction   and   guidelines.   The   information developed specifically for Navy use is as follows: 29 CFR   1910   (OSHA),   40   CFR   240-262   (series), OPNAVINST  5090.1  (series),  Environmental    and Natural   Resources   Protection   Manual;   NAVFAC MO-213,   Solid  Waste  Management;  and  NAVFAC DM 5.10, Solid Waste Disposal. HAZARDOUS  MATERIAL  CONTROL The   Hazardous   Material   Control   Program   is   a Navy-wide  program  that  enforces  the  correct  storage, handling,   usage,   and   disposition   of   hazardous material.   Hazardous   waste   disposal   is   a   serious concern  to  the  NCF  today.  Cleaners,  acids,  mastics, sealers, and even paints are just a few of the hazardous materials that may be present in your shop or on your project site. As a crew leader, you are responsible for the safety and protection of your crew. PROPERTIES  OF  HAZARDOUS  WASTE Few  discarded  materials  are  so  compatible  with the  environment  or  so  inert  as  to  have  no  short-  or long-term   impact.   Hazards   that   appear   minor   may have  unexpected  impacts  long  after  disposal.  When two  or  more  hazards  pertain  to  a  material,  the  lesser may  not  receive  the  necessary  consideration.  When two   discarded   substances   are   mixed,   a   chemical reaction   with   severe   and   unexpected   consequences may result. Since   waste   is   generally   a   mixture   of   many components,  its  physical  and  chemical  properties cannot   be   defined   with   any   degree   of   accuracy. Whenever possible, the approximate composition of a hazardous   waste   should   be   ascertained   from   the originating source or from the manifest accompanying the   waste   being   transported.   Generally,   when   one component  predominates,  the  physical  and  chemical properties of the waste mixture are nearly those of the major  component.  This  is  not  true  for  the  hazardous properties  of  waste  mixtures  consisting  of  relatively harmless   major   components   and   small   amounts   of highly   toxic,   radioactive,   or   etiologically (disease-producing)  active  components.  The  hazard, in this case, is determined by the smaller component. The  EPA  defines  hazardous  solid  waste  as  any material that has the potential to produce the following results: Cause, or significantly contribute to, an increase in   mortality   or   any   serious,   reversible,   or incapacitating reversible illness. Pose a substantial hazard to human health or the environment  when  the  hazardous  material  is improperly   stored,   treated,   transported,   or disposed  of. By  EPA  standards,  the  determining  factor  for  a material  to  be  classified  as  hazardous  waste  is  that  it must  meet  one  or  more  of  the  conditions  of  being ignitable,  corrosive,  reactive,  or  toxic,  as  covered  in the  following  information. Ignitable It  is  a  liquid,  other  than  an  aqueous  solution, containing less than 24 percent alcohol by volume and has a closed-cup flash point of less than 60°C (140°F). It  is  not  a  liquid,  but  is  capable  under  standard temperature  and  pressure  of  causing  fire  through friction,   absorption   of   moisture,   or   spontaneous chemical   changes,   and   when   ignited,   burns   so vigorously and persistently that it creates a hazard. It   is   an   ignitable,   flammable   compressed   gas, which  is  defined  as  a  gas  that  forms  a  flammable mixture  when  mixed  with  air  at  a  concentration  less than  13  percent  (by  volume)  or  has  a  flammability range  with  air  that  is  greater  than  12  percent, regardless of its lower flammable limit. It is an oxidizer, such as a chlorate, permanganate, inorganic peroxide, nitrocarbo nitrate, or a nitrate that yields  oxygen  readily,  and  stimulates  the  combustion of organic matter. Corrosive It is a watery solution with a pH less than or equal to 2 or greater than or equal to 12.5. It  is  a  liquid,  that  corrodes  steel  at  a  rate  greater than 6.35 mm (0.25 inch) per year at a test temperature of 55°C (130°F). Reactivity It   is   normally   unstable   and   readily   undergoes violent  change  without  detonating. 1-22
