Reason: switch-off instrument will not harm anymore to us.

2. The solvents used in the lab are highly flammable, posing a fire hazard.

Reason: Tightly closed lid can prevent exposure and switch-on exhaust fan will cover risk of fire.

3. Solutions are prepared in nitric acid, posing a risk for eye injuries.

Reason: Wearing googles will prevent eye injury.

4. But, last one SCN- is highly toxic and must be handled with special care.

Reason: We cannot escape from odours of this toxic chemicals, absorbs through skin, risk of even premature death is possible with highly toxic chemicals. hence this is considered to be utmost handled with special care.
