  Definition of Industrial Hygiene

  Industrial Hygiene: Science and art devoted to
  the anticipation, recognition, evaluation,
  prevention, and control of those environmental
  factors or stresses arising in or from the workplace
  which may cause sickness, impaired health and
  well being, or significant discomfort among
  workers or among citizens of the community.*

Respiratory Protection
• “Avoid breathing dust”

 Respiratory protection:
 • A respiratory protection program meeting OSHA 1910.134 and
   ANSI Z88.2 requirements or equivalent must be followed
   whenever workplace conditions warrant a respirator's use.
 •   None required if airborne concentrations are maintained below the
     exposure limit listed in Exposure Limit Information.
 •   When dusty conditions are encountered, wear a properly-fitted
     NIOSH-approved (or equivalent) half-mask, air-purifying
     respirator. Air-purifying respirators should be equipped with
     NIOSH-approved (or equivalent) N95 filters. If oil mist is present,
     use R95 or P95 filters.
Personal Protective Equipment
• “Use impervious gloves.”

 Hand Protection
 • NOTE: Material is a potential skin sensitizer.
 • The gloves listed below may provide protection against permeation.
   Gloves of other chemically resistant materials may not provide
   adequate protection:
     – Butyl rubber or Nitrile
 •   Gloves should be removed and replaced immediately if there is any
     indication of degradation or chemical breakthrough. Rinse and
     remove gloves immediately after use. Wash hands with soap and
Spill Clean-up
• “Clean up spills immediately.”

 Methods for cleaning up:
 • Adsorb the spill with spill pillows or inert solids such as clay or
   vermiculite, and transfer contaminated materials to suitable
   containers for disposal.
 • Deactivate spill area with freshly prepared solution of 5% sodium
   bicarbonate and 5% sodium hypochlorite in water. Apply solution
   to the spill area at a ratio of 10 volumes deactivation solution per
   estimated volume of spill to deactivate any residual active
   ingredient. Let stand for 30 minutes.
 • DO NOT add deactivation solution to the waste pail to deactivate
   the adsorbed material.
• “Use local ventilation.”

 Engineering measures:
 • Use explosion-proof local exhaust ventilation with a
   minimum capture velocity of 150 ft/min (0.75 m/sec) at
   the point of dust or mist evolution.
 • Refer to the current edition of Industrial Ventilation: A
   Manual of Recommended Practice published by the
   American Conference of Governmental Industrial
   Hygienists for information on the design, installation,
   use, and maintenance of exhaust systems.

New Challenges – Chemical Process Safety
    Washington, DC, March 25, 2004 - Carolyn Merritt, Chairman of the
    U.S. Chemical Safety and Hazard Investigation Board (CSB) told a
    Congressional committee that:

•   The safety information accompanying chemical products delivered to industrial
    plants frequently is deficient, leading to avoidable deaths and injuries.
•   "Deficiencies in hazard communication and Material Safety Data Sheets are
    among the common causes of major chemical accidents that result in loss of
    life, serious injures, and damage to property and the environment."
•   Deficiencies in communicating hazards on the data sheets were cited in 10 of
    19 investigation reports (1998-2004). The deficiencies were found to be an
    actual root cause, contributing cause, or major causal factor in nine of the ten.
•   The Chairman in particular cited the inadequacy of information in data sheets
    concerning combustible dust dangers that occur in certain chemical

MSDS - Who’s the audience?
  The AIHA fully supports one MSDS format for all target
  audiences. The AIHA encourages the use of international
  standards/guidelines (including recommended phrases and
  symbols) that allow MSDS preparers to communicate hazards in an
  understandable way to each of the various MSDS users. The AIHA
  recognizes that providing information on an MSDS, beyond that
  required by the OSHA Hazard Communication Standard, is
  necessary to fulfill needs of the variety of target audiences (e.g.,
  transportation, global inventory status, waste disposal
  information). Specific formatting and content guidelines or
  regulations can facilitate this need. One must remember that the
  MSDS is a reference document meant to be used with education
  and labeling to communicate hazards. It is not meant to be a
  stand-alone document.
