<br /> On-site overnight storage of non ❑For CFTAS-applicable chemical storage,a safety and chemical management plan must be prepared and
<br /> waste chemical product at quantity reviewed by a H&S Professional before bringing material to the site.(Does not apply to materials brought on to
<br /> >25 gal(115L)or>250 lbs.(115 kg) the site for daily work purposes and transported away at the end of each day)
<br /> COMPRESSED GAS CYLINDERS ❑Secure cylinders upright,caps on when not in use.
<br /> ❑Flammable ❑Handle with care;use and store cylinders in a manner and location to prevent damage.
<br /> ❑Non-flammable ❑Propane cylinders not in use must be stored outdoors in a cage or similar secure ventilated enclosure.
<br /> ❑Toxic ❑Ensure acetylene cylinders are NOT secured to steel arc welding bench.
<br /> ❑Asphyxiant ❑Segregate oxygen and fuel gases by distance(20')or fire-rated barrier.
<br /> ❑Oxygen ❑Control ignition sources.
<br /> ❑"No smoking"signage at cylinder storage area for flammable gases.
<br /> FLAMMABLE/COMBUSTIBLE ❑Use proper fuel safety can(metal fuel container with self-closing spout and flame arrestor preferred).
<br /> LIQUIDS ❑Control/remove ignition sources near storage and use areas.
<br /> ❑Grounding and bonding where appropriate.
<br /> ❑Ensure a Type B or ABC fire extinguisher is readily available.
<br /> ® ACIDS,CAUSTICS,OTHER N Use appropriate protection for eyes/face(goggles/face shield)and skin(gloves,sleeves,apron).
<br /> CORROSIVES ❑Use eyewash,deluge shower,drench hose,hand washing(with water),as appropriate.
<br /> ❑For severe eye hazards(due to high corrosivity,large quantity),15-min.eyewash required.
<br /> TOXIC ❑For toxic substances,use/store in a manner to control exposure hazards(inhalation,ingestion,skin contact,
<br /> skin absorption);use active ventilation and/or PPE as appropriate.
<br /> ® EMISSIONS FROM FUEL N Position outdoor personnel upwind of exhaust source.
<br /> COMBUSTION,HOT PROCESSES N Avoid"idling"of equipment when not in use.
<br /> ❑Gasoline N Use passive ventilation(air infiltration/air currents)to disperse atmospheric hazards in breathing zone.
<br /> ❑Diesel ❑Use dilution ventilation(blowers/fans)to provide fresh air to work area and dissipate atmospheric hazards.
<br /> ❑Propane/Natural Gas ❑Use exhaust ventilation(hood/duct/exhaust stack/blower)to capture/divert exhaust from work area.
<br /> ❑Welding/cutting/hot work ❑Use respiratory protection for high levels of smoke,exhaust particulates,soot.
<br /> N Vehicle/equipment exhaust ❑Conduct air monitoring as appropriate;see Part E,"Air Monitoring,Worker Exposure Monitoring."
