POTENTIAL HEALTH EFFECTS
  c2 h3 Y: G* {# G3 D5 G" J6 q9 zACUTE HEALTH EFFECTS
SWALLOWED
The material may produce chemical burns within the oral cavity and gastrointestinal tract
following ingestion.
" s& D, Y2 |/ R; G% i  E! n  uEYE
There is evidence that material may produce eye irritation in some persons and produce
4 Z" `5 U( c* [* Q( i5 ieye damage 24 hours or more after instillation. Severe inflammation may be expected with
! u# t* U& C# i( L+ p# Spain. There may be damage to the cornea. Unless treatment is prompt and adequate there
may be permanent loss of vision. Conjunctivitis can occur following repeated exposure.
SKIN
This material can cause inflammation of the skin oncontact in some persons.
The material may accentuate any pre-existing dermatitis condition.
Skin contact is not thought to have harmful health effects, however the material may
still produce health damage following entry through wounds, lesions or abrasions.
Reactions may not occur on exposure but response may be delayed with symptoms only
appearing many hours later.
INHALED
The material can cause respiratory irritation in some persons. The body's response to
such irritation can cause further lung damage.
Persons with impaired respiratory function, airway diseases and conditions such as
% o( ~- M! R) E% [+ e; G) Qemphysema or chronic bronchitis, may incur further disability if excessive concentrations
of particulate are inhaled.
CHRONIC HEALTH EFFECTS
( P2 U7 {6 I7 G, jLong term exposure to high dust concentrations may cause changes in lung function i.e.
pneumoconiosis; caused by particles less than 0.5 micron penetrating and remaining in the
lung. Prime symptom is breathlessness; lung shadows show on X-ray.
Asthma-like symptoms may continue for months or even years after exposure to the material
  J- Q5 Q! {6 X4 l! Hceases. This may be due to a non-allergenic condition known as reactive airways
, c1 v/ v+ O' K0 q; C& c5 Xdysfunction syndrome (RADS) which can occur following exposure to high levels of highly
4 q4 n8 Q1 h6 q8 \+ k8 i  Oirritating compound. Key criteria for the diagnosis of RADS include the absence of
preceding respiratory disease, in a non-atopic individual, with abrupt onset of
persistent asthma-like symptoms within minutes to hours of a documented exposure to the
irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to
severe bronchial hyperreactivity on methacholine challenge testing and the lack of
7 [% b! h5 \8 ~1 r0 m9 O( zminimal lymphocytic inflammation, without eosinophilia, have also been included in the
; }/ J& K1 }: C8 ^! f- wcriteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an
infrequent disorder with rates related to the concentration of and duration of exposure
to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that
occurs as result of exposure due to high concentrations of irritating substance (often
3 U2 z" w7 @$ a9 f/ E# P& pparticulate in nature) and is completely reversible after exposure ceases. The disorder
; D6 H3 Q" F+ v0 b$ |is characterised by dyspnea, cough and mucus production.

may be required in specific circumstances. If risk of overexposure exists, wear an

adequate ventilation in warehouse or closed storage areas. Air contaminants generated in
the workplace possess varying "escape" velocities which, in turn, determine the "capture

Type of Contaminant: Air Speed: solvent, vapors, degreasing etc., evaporating from tank (in still air). 0.25-0.5 m/s (50-100 f/min) aerosols, fumes from pouring operations, intermittent container filling, low speed conveyer transfers, welding, spray drift, plating acid fumes, pickling (released at low velocity into zone of active generation) 0.5-1 m/s (100-200 f/min.) direct spray, spray painting in shallow booths, drum filling, conveyer loading, crusher dusts, gas discharge (active generation into zone of rapid air motion) 1-2.5 m/s (200-500 f/min.) grinding, abrasive blasting, tumbling, high speed wheel generated dusts (released at high initial velocity into zone of very high rapid air motion). 2.5-10 m/s (500-2000 f/min.)

Within each range the appropriate value depends on:

Lower end of the range Upper end of the range 1: Room air currents minimal or favorable to capture 1: Disturbing room air currents 2: Contaminants of low toxicity or of nuisance value only. 2: Contaminants of high toxicity 3: Intermittent, low production. 3: High production, heavy use 4: Large hood or large air mass in motion 4: Small hood-local control only
