|
Handling and Storage |
|
|
|
Handling
|
Avoid creating any dust. Do not
smoke. During handling electrostatic charges can accumulate (see BS 5958
for advice on the control of static.)
|
|
|
|
Storage |

Exposure Control / Personal Protection
|
|
|
|
Occupational Exposure Standards:
|
|
|
|
Synthetic amorphous silica |
Silica amorphous, total
inhalable dust: UK EH40: OES 6mg/m3 8h TWA.
Silica amorphous, respirable
dust: UK EH40: OES 2.4mg/m3 8h TWA.
Silica Gel: ACGIH: TLV 10mg/m3
8h TWA.
Activation agent: ACGIH:
0.5mg/m3 8h TWA.
|
|
|
|
Engineering Control Measures |
Engineering methods to prevent
or control exposure are preferred. Methods include process or personnel
enclosure, mechanical ventilation (dilution and ocal exhaust), and control
of process conditions. |
|
|
|
Respiratory Protection |
Avoid inhalation of dust. Wear
suitable respiratory protective equipment if working in confined spaces
with inadequate ventilation or whenever there is any risk of the exposure
limits being exceeded. |
|
|
|
Hand Protection
Eyes Protection
Protection During Application |
Wear protective gloves.
Wear suitable eye protection.
Handle in well ventilated
conditions in accordance with good industrial hygiene and safety
practices. |

Toxicological Information
|
|
|
Toxicity |
The lethal dose for humans for
synthetic amorphous silica is estimated at over
15,000mg/kg. |
|
|
Health Effects Inhalation |
Synthetic amorphous silica gel
has little adverse effect on lungs and does not produce significant
disease or toxic effect when exposure is kept below the permitted limits.
However existing medical conditions (eg asthma, bronchitis) may be
aggravated by exposure to dust. Effects of dust may be greater, and occur
at lower levels of exposure in smokers compared to non-smokers. |
|
|
Eye Contact |
Dust may cause discomfort and
mild irritation. |
|
|
Skin Contact |
Dust may have a drying effect
on the skin. |
|
|
Carcinogenicity |
Amorphous silica is not
classifiable as to its carcinogenicity to humans (Group 3). |
