Part 7: Handling and storage

Operation precautions:

Closed operation to provide good natural ventilation conditions.

Keep away from fire and heat sources. 

Smoking is strictly prohibited in the workplace.

Prevent vapors from leaking into the workplace air.

Avoid contact with acids and alkalis.

When handling, load and unload carefully to prevent damage to packaging and containers.

With varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.

Storage precautions: 

Store in a cool, ventilated warehouse.

Keep away from fire and heat sources.

Keep the container tightly sealed.

Open storage, avoid mixed storage.

Use explosion-proof lighting and ventilation facilities.

It is prohibited to use mechanical equipment and tools that are prone to sparks.

The storage area should be with emergency release equipment and suitable containment materials.

Section 8: Exposure controls/personal protection

Maximum allowable concentration:

Monitoring method: Gas chromatography.

Engineering control: The production process is sealed and ventilation is enhanced. Respiratory system protection: When the concentration in the air exceeds the standard, wear a self-priming filter gas mask (half mask). During emergency rescue or evacuation, air respirators or oxygen respirators must worn.

Eye protection: Wear chemical safety glasses.

Body protection: Wear anti-toxic work clothes.

Hand protection: Wear rubber and oil-resistant gloves.

Other protection: Smoking, eating, and drinking are prohibited at the work site. Avoid drinking alcoholic beverages before work. After work, shower and change clothes. Undertake pre-employment and periodic physical exams.
