What should be avoided in chemistry laboratory?
Keep your hands away from your face, eyes, mouth, and body while using chemicals. Food and drink, open or closed, should never be brought into the labora- tory or chemical storage area. Never use laboratory glassware for eating or drinking purposes. Do not apply cosmetics while in the laboratory or storage area.
What chemical health hazard is most harmful to someone who is pregnant?

What harmful substances can pass from mother to baby?
Tobacco, alcohol and drugs can have harmful effects on anyone’s health. When a pregnant or nursing woman uses these substances, her baby also is exposed to them, for all substances cross the placenta through the umbilical cord and enter into the baby’s bloodstream.

Can strong chemical smells affect pregnancy?
Avoid pesticides, household cleaners, and paint. Fumes from these substances can be harmful to a baby, especially in the first trimester of pregnancy. Use chemical-free cleaning alternatives while you’re pregnant. If you must use chemical cleaners, wear gloves, ventilate the area, and avoid inhaling fumes.

- high doses of vitamin A.
- lithium.
- male hormones.
What can accidentally cause a miscarriage?
- Infection.
- Exposure to TORCH diseases.
- Hormonal imbalances.
