Hazmats can be classified accrding t the hazard as explsives; cmpressed gases, including txic r flammable gases; flammable liquids; flammable slids; xidizing substances; txic materials; radiactive material; and crrsive substances. Guidance n the transprt f hazardus materials is cvered in Sectin 3 f this dcument. When a hazardus material is n lnger usable fr its riginal purpse and is intended fr dispsal, but still has hazardus prperties, it is cnsidered a hazardus waste (see Sectin 1.4). This guidance is intended t be applied in cnjunctin with traditinal ccupatinal health and safety and emergency preparedness prgrams which are included in Sectin 2.0 n Occupatinal Health and Safety Management, and Sectin 3.7 n Emergency Preparedness and Respnse. Guidance n the Transprt f Hazardus Materials is prvided in Sectin 3.5. This sectin is divided int tw main subsectins: General Hazardus Materials Management: Guidance applicable t all prjects r facilities that handle r stre any quantity f hazardus materials. Management f Majr Hazards: Additinal guidance fr prjects r facilities that stre r handle hazardus materials at, r abve, threshld quantities 39, and thus require special treatment t prevent accidents such as fire, explsins, leaks r spills, and t prepare and respnd t emergencies. The verall bjective f hazardus materials management is t avid r, when avidance is nt feasible, minimize uncntrlled releases f hazardus materials r accidents (including explsin and fire) during their prductin, handling, strage and use. This bjective can be achieved by: 39 Fr examples, threshld quantities shuld be thse established fr emergency planning purpses such as prvided in the US Envirnmental Prtectin Agency.

MSDSs shuld be readily accessible t emplyees in their lcal language. Definitin and implementatin f permitted maintenance activities, such as ht wrk r cnfined space entries Prvisin f suitable persnal prtectin equipment (PPE) (ftwear, masks, prtective clthing and gggles in apprpriate areas), emergency eyewash and shwer statins, ventilatin systems, and sanitary facilities Mnitring and recrd-keeping activities, including audit prcedures designed t verify and recrd the effectiveness f preventin and cntrl f expsure t ccupatinal hazards, and maintaining accident and incident investigatin reprts n file fr a perid f at least five years Prcess Knwledge and Dcumentatin The Hazardus Materials Management Plan shuld be incrprated int, and cnsistent with, the ther elements f the facility ES/OHS MS and include: Written prcess safety parameters (i.e., hazards f the chemical substances, safety equipment specificatins, safe peratin ranges fr temperature, pressure, and ther applicable parameters, evaluatin f the cnsequences f deviatins, etc.) Written perating prcedures Cmpliance audit prcedures 42 MSDSs are prduced by the manufacturer, but might nt be prepared fr chemical intermediates that are nt distributed in cmmerce. In these cases, emplyers still need t prvide wrkers with equivalent infrmatin. Preventive Measures Hazardus Materials Transfer Uncntrlled releases f hazardus materials may result frm small cumulative events, r frm mre significant equipment failure assciated with events such as manual r mechanical transfer between strage systems r prcess equipment. Recmmended practices t prevent hazardus material releases frm prcesses include: Use f dedicated fittings, pipes, and hses specific t materials in tanks (e.g., all acids use ne type f cnnectin, all caustics use anther), and maintaining prcedures t prevent additin f hazardus materials t incrrect tanks Use f transfer equipment that is cmpatible and suitable fr the characteristics f the materials transferred and designed t ensure safe transfer Regular inspectin, maintenance and repair f fittings, pipes and hses Prvisin f secndary cntainment, drip trays r ther verflw and drip cntainment measures, fr hazardus materials cntainers at cnnectin pints r ther pssible verflw pints. Overfill Prtectin Overfills f vessels and tanks shuld be prevented as they are amng the mst cmmn causes f spills resulting in sil and water cntaminatin, and amng the easiest t prevent. Recmmended verfill prtectin measures include: Prepare written prcedures fr transfer peratins that includes a checklist f measures t fllw during filling peratins and the use f filling peratrs trained in these prcedures Installatin f gauges n tanks t measure vlume inside Use f dripless hse cnnectins fr vehicle tank and fixed cnnectins with strage tanks APRIL 30,

Recmmended preventin practices include: Strage f incmpatible materials (acids, bases, flammables, xidizers, reactive chemicals) in separate areas, and with cntainment facilities separating material strage areas Prvisin f material-specific strage fr extremely hazardus r reactive materials Use f flame arresting devices n vents frm flammable strage cntainers Prvisin f grunding and lightning prtectin fr tank farms, transfer statins, and ther equipment that handles flammable materials Selectin f materials f cnstructin cmpatible with prducts stred fr all parts f strage and delivery systems, and aviding reuse f tanks fr different prducts withut checking material cmpatibility Strage f hazardus materials in an area f the facility separated frm the main prductin wrks. Where prximity is unavidable, physical separatin shuld be prvided using structures designed t prevent fire, explsin, spill, and ther emergency situatins frm affecting facility peratins Prhibitin f all surces f ignitin frm areas near flammable strage tanks Cntrl Measures Secndary Cntainment (Liquids) A critical aspect fr cntrlling accidental releases f liquid hazardus materials during strage and transfer is the prvisin f secndary cntainment. It is nt necessary fr secndary cntainment methds t meet lng term material cmpatibility as with primary strage and piping, but their design and cnstructin shuld hld released materials effectively until they can be detected and safely recvered. Apprpriate secndary cntainment structures cnsist f berms, dikes, r walls capable f cntaining the larger f 110 percent f the largest tank r 25% percent f the cmbined tank vlumes in areas with abve-grund tanks with a ttal strage vlume equal r greater than 1,000 liters and will be made f impervius, chemically resistant material. Secndary cntainment design shuld als cnsider means t prevent cntact between incmpatible materials in the event f a release. Other secndary cntainment measures that shuld be applied depending n site-specific cnditins include: Transfer f hazardus materials frm vehicle tanks t strage in areas with surfaces sufficiently impervius t avid lss t the envirnment and slped t a cllectin r a cntainment structure nt cnnected t municipal wastewater/strmwater cllectin system Where it is nt practical t prvide permanent, dedicated cntainment structures fr transfer peratins, ne r mre alternative frms f spill cntainment shuld be prvided, such as prtable drain cvers (which can be deplyed fr the duratin f the peratins), autmatic shut-ff valves n strm water basins, r shut ff valves in drainage r sewer facilities, cmbined with il-water separatrs APRIL 30,

If dublewalled systems are used, they shuld prvide a means f detecting leaks between the tw walls. Strage Tank and Piping Leak Detectin Leak detectin may be used in cnjunctin with secndary cntainment, particularly in high-risk lcatins 43. Leak detectin is especially imprtant in situatins where secndary cntainment is nt feasible r practicable, such as in lng pipe runs. Acceptable leak detectin methds include: Use f autmatic pressure lss detectrs n pressurized r lng distance piping Use f apprved r certified integrity testing methds n piping r tank systems, at regular intervals Cnsidering the use f SCADA 44 if financially feasible 43 High-risk lcatins are places where the release f prduct frm the strage system culd result in the cntaminatin f drinking water surce r thse lcated in water resurce prtectin areas as designated by lcal authrities. Undergrund Strage Tanks (USTs) 45 Althugh there are many envirnmental and safety advantages f undergrund strage f hazardus materials, including reduced risk f fire r explsin, and lwer vapr lsses int the atmsphere, leaks f hazardus materials can g undetected fr lng perids f time with ptential fr sil and grundwater cntaminatin. Examples f techniques t manage these risks include: Aviding use f USTs fr strage f highly sluble rganic materials Assessing lcal sil crrsin ptential, and installing and maintaining cathdic prtectin (r equivalent rust prtectin) fr steel tanks Fr new installatins, installing impermeable liners r structures (e.g., cncrete vaults) under and arund tanks and lines that direct any leaked prduct t mnitring prts at the lwest pint f the liner r structure Mnitring the surface abve any tank fr indicatins f sil mvement Recnciling tank cntents by measuring the vlume in stre with the expected vlume, given the stred quantity at last stcking, and deliveries t and withdrawals frm the stre Testing integrity by vlumetric, vacuum, acustic, tracers, r ther means n all tanks at regular intervals Cnsidering the mnitring grundwater f quality dwn gradient f lcatins where multiple USTs are in use Evaluating the risk f existing UST in newly acquired facilities t determine if upgrades are required fr USTs that will be cntinued t be used, including replacement with new systems r permanent clsure f abandned USTs.
