Precautions for limited space operation management system

Before entering a limited space for work, the limited space must be cleaned and replaced, and the following requirements must be met:

Before cleaning, workers must be familiar with the physical and chemical properties of substances present in a limited space and the safety technical instructions of related materials.

When cleaning, you should first use inert gases such as nitrogen to protect or replace flammable, explosive or toxic and harmful media; then, use steam or hot water as the cleaning medium. There should be no blind ends during cleaning, and the cleaning order is from high to low. If there are materials that are difficult to clean with steam or hot water, appropriate solvents should be used for cleaning, with non-toxic substances preferred; clean them with steam or hot water again.

After cleaning, air replacement should be carried out, and the levels of oxygen and other dangerous gases should be monitored at any time.

When using compressed air for replacement, blind end replacement should be considered, and the flow rate should be controlled to less than 2 cubic meters/minute.

The oxygen content after replacement should reach 18-21%.

The concentration of toxic, harmful and other dangerous gases in limited spaces complies with GB Z2-2002 regulations.
