you should not pressurize empty сonteiners OHS

How do you say in Russian:
you should not pressurize empty сonteiners

This is from base oil MSDS, regulations on waste handling:
"Empty storage conteiners (of hazardous liquid) can contain residues of hazardous materials and therefore you should not pressurize, cut or weld them."
