Mechanical Hygiene in the BP Oil Spill Event: What's Public and What We Should Learn From the Event Thomas Grumbles, CIH Senior Consultant Cardno ENTRIX California Industrial Hygiene Council December 6, 2010

Slide 2

The most "open" crisis reaction occasion to date

Slide 3

Scope Of Work At the pinnacle of action 47,848 laborers 8,044 vessels 123 air ship   $65 million/day September 20 25,200 specialists 2,600 vessels many airplane November 12 9,300 specialists 135 vessels $27 million/day Federal reaction drove by the U.S. Drift Guard under the National Contingency Plan

Slide 4

BP IH Activity Source system not the same as on shore/close shore methodology Source Strategy ( BP Source Monitoring Strategy ) On-Shore Strategy ( BP Onshore Monitoring Strategy ) Sampling results are distributed in two ways: ( BP IH Data ) Summary shape Full points of interest Personal observing outcomes for the most part show there are no noteworthy exposures to airborne centralizations of chemicals of intrigue >200 mechanical hygienists and experts to screen range and individual exposures in the recognized work zones As of fifteenth October 2010, ~70 modern hygienists offering help to the continuous reclamation ~23,000 individual specimens gathered

Slide 6

Area and faculty checking amid: On Shore and Near Shore Monitoring Strategy 4 "strike groups" PBZ for BTEX, Total hydrocarbons (THC) Area for VOC's, CO, LEL and Benzene Priority was disinfecting action Goal to test 10% of distinguished gatherings Professional judgment for extra observing Action levels created for taking particular control activities Beach tidy up Vessel sterilization Wildlife purification Skimming operations Boom sending and recovery operations Area checking in light of smell dissensions

Slide 7

Off Shore (Source) Monitoring Strategy Monitoring arrangement reason: Protect potential downwind receptors Protect laborer wellbeing Support safe operations with undertaking checking Action levels produced for taking particular control activities Every vessel alloted to the source region was prepared for observing

Slide 8

Off Shore (Source) Monitoring Strategy VOC's (THC) Benzene H2S Oxygen LEL CO PM10 SO2 Area and staff observing

Slide 9

BP Sampling Results: Summary

Slide 10

BP Sampling Results: Full Details

Slide 11

OSHA Activity through 10/1/10 OSHA found the middle value of more than 146 experts all through the Gulf Region amid the occasion The Agency built up an inspecting convention and procedure and took tests bringing about more than 5,731 presentation appraisals ( introduction evaluations ) To date, no air examining by OSHA has identified any dangerous substance at levels of concern. (Spill Home Page) All OSHA results are posted (inspecting comes about) OSHA staff made more than 4,266 site visits to: vessels of chance organizing ranges sterilization locales seaward and inland tidy up exercises

OSHA Activity through 10/1/10 OSHA arrived at the midpoint of more than 146 experts all through the Gulf Region amid the occasion The Agency built up an examining convention and system and has taken examples bringing about more than 5,731 presentation evaluations ( introduction appraisals ) To date, no air testing by OSHA has distinguished any perilous substance at levels of concern. (Spill Home Page) All OSHA results are posted (inspecting comes about) OSHA staff made more than 4,266 site visits to vessels of chance arranging zone purification destinations seaward and coastal tidy up exercises

Slide 15

OSHA Sampling Strategy: What perils to assess in an occasion this way? The greater part of the cleanup specialists are presented to "weathered oil" more unpredictable substances have vanished Potential wellbeing impacts from breathing in other non oil chemicals oil dispersants, cleaning operators, and others are a continuous worry Among the many perils laborers confront -, for example, falls, suffocating, weariness, sharp questions and creature chomps - the main wellbeing concern was warmth worry with more than 700 episodes detailed by 8/16

Slide 16

OSHA Sampling Strategy: Systematic ways to deal with evaluating dangers OSHA concocted a precise way to deal with survey risks, a Sampling Strategy , to portray and archive dangers of generally watched work exercises "OSHA is likewise dissecting the "soup" of raw petroleum, oil by-items, dispersants, and whatever other material to figure out what dangers the blend may display laborers as they react to and cleanup the oil slick"

Slide 19

APPLICABLE OEL'S OSHA perceives that the majority of its PELs are obsolete and insufficient measures of specialist security. Unrefined petroleum is an unpredictable blend of concoction constituents that are not effectively tended to by introduction limits for individual substances In portraying laborer presentation OSHA rather depends on additional up and coming prescribed defensive cutoff points set by associations, for example, NIOSH, ACGIH, and AIHA, not on the more established, less defensive PELS Results of air checking are contrasted with the most minimal known OEL for the recorded contaminant for motivations behind hazard appraisal and defensive gear suggestions

Slide 20

NIOSH Health Hazard Evaluations (HHEs)

Slide 21

NIOSH HHEs Evaluation of the hospitalization of  7  Fishermen on May  26 Conclusion: Given the different depictions and unspecified wellsprings of the announced scents, the indeterminate planning of the manifestations in connection to utilization of another cleaner, and indications that could be identified with an assortment of causes: it  is  unlikely  that  a  single  specific  trigger  for the detailed side effects can be resolved Dispersant  use  appears  unlikely  to  be  the  source  of the side effects side effects  were  more  likely  to  have  been  aggravated  by  several  contributing  factors,  including  unpleasant  odors,  heat, and exhaustion.

Slide 22

NIOSH HHEs June  4‐5  evaluation of M/V International Peace and MV  Warrior  Dispersant  Mission Industrial  hygiene  surveys,  health  symptom  survey and  medical  interviews  during  a  small  scale dispersant mission PBZ  and  area  air  concentrations  of  the contaminants measured  were  all  well  below  OELs NIOSH  investigators  did  observe  the  potential  for  dermal contact with  the  dispersant   On June 14-16 PBZ and zone air groupings of the contaminants measured amid an oil skimming mission on board the M/V Queen Bee were underneath word related presentation limits

Slide 23

NIOSH HHEs June 8–10 assessment of In-situ Oil Burns Based on examining directed more than two days on start pontoons and vessels towing blast amid smolders, NIOSH agents discovered exposures for all mixes inspected to be well beneath appropriate OELs One special case: top exposures to CO recorded on the vessels because of fumes from gas fueled motors

Slide 24

NIOSH HHEs June 25 assessment of Barge Oil Vacuuming Operations in Coup Abel Pass Louisiana was led Limited action to test Safety and clamor perceptions: For instance: A couple of laborers wore wellbeing outfits. The saddles were not attached off to any structure on the freight ships to capture the specialists' fall

Slide 25

NIOSH HHEs June 21-25 modern cleanliness overviews and self-directed wellbeing manifestation reviews on board two vessels at the site of the oil discharge Airborne focuses for all contaminants assessed were well beneath relevant OELs Some expansion in psychosocial side effects, gave an account of one vessel

Slide 26

NIOSH HHEs September assessment of 1,899 laborers at 67 work destinations in Louisiana, Alabama, Florida, and Mississippi Surveys and talks with Heat stress was the essential word related wellbeing peril for most shore cleaning laborers Ergonomic dangers from the one of a kind work required to clean oil buildup from sandy shorelines Use of instruments that were never intended for this undertaking Workers had outlined "custom made" devices that were more successful than standard apparatuses

Slide 27

NIOSH HHEs October assessment and quantitative presentation evaluation at two sterilization locales in Port Fourchon, Louisiana Heat stress was the essential word related wellbeing risk for most repair/purification and waste administration specialists exacerbated by the utilization of individual defensive gear Where measured, airborne centralizations of measured contaminants, including 2-butoxyethanol and other glycol ethers, limonene, benzene, ethyl benzene, toluene, xylenes , add up to hydrocarbons, diesel fumes, PAHs, and CO were all well underneath OELs Monitoring demonstrated the potential for clamor exposures over the NIOSH REL amid weight washing Repair/disinfecting and squander administration specialists confronted ergonomic perils from extraordinary work exercises, for example, dealing with and moving blasts and other hardware to be cleaned and the activities related with working the weight washers

Slide 28

Lessons Learned Communication of a lot of introduction information to obscure groups of onlookers is … ..troublesome Conclusions from information for numerous differing and always showing signs of change occasions is a test… .persistence is required Traditional IH checking procedures … may not suffice for huge scale occasions general society nature and political weights required in prominent occasions can bring about great science being "underutilized"

Slide 29

Communicating Monitoring Results BP June month to month rundown report Graph showed 210 specimens of 893 indicated exposures between non recognize and 10 ppm for 2-butoxyethanol July 9 New York Times article The Valdez-connected compound 2-butoxyethanol was identified at levels up to 10 sections for every million (ppm) in more than 20 percent of seaward responders . Week of July 16 OSHA reply The feature depends on a wrong elucidation of a deceptive diagram delivered by BP. OSHA's examination of the crude information achieves an altogether different conclusion Sampling is not done arbitrarily and is not really illustrative of all uncovered specialist
