Ideally, other engineering controls should lessen the amount of dust collecting on the floor and being tracked onto the sticky mat, unlike this example. [3] Other non-ventilation engineering controls in general cover a range of control measures, such as guards and barricades, material treatment, or additives.

Examples of non-ventilation engineering controls include placing equipment that may release nanomaterials in a separate room, and placing walk-off sticky mats at room exits. [5]: 9–11 Antistatic devices can be used when handling nanomaterials to reduce their electrostatic charge, making them less likely to disperse or adhere to clothing.
Administrative controls do not remove hazards, but limit or prevent people's exposure to the hazards, such as completing road construction at night when fewer people are driving. [5] Administrative controls are ranked lower than elimination, substitution, and engineering controls because they do not directly remove or reduce workplace hazards.
A relief valve DN25 on cooling water pipe from heat exchanger Schematic diagram of a conventional spring-loaded pressure relief valve. A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.
Since warm air normally rises, this method usually requires venting at the top or sides of the casing to be effective. Forced air cooling If there is more air being forced into a system than being pumped out (due to an imbalance in the number of fans), this is referred to as a 'positive' airflow, as the pressure inside the unit is higher than ...
Black Friday and Cyber Monday are the best times to shop for holiday gifts. Nearly every product goes on sale, whether you're shopping for mom (get her a Kate Spade tote) or your grandchild (get ...
Vented balance safety enclosures are used in pharmaceutical, chemical, biological, and toxicological laboratories to provide maximum containment for weighing operations in weighing scales. Fume hoods , also known as laboratory chemical hoods, are one of the most important and widely used engineering controls to protect laboratory workers.
