Si-OAT coolants mix silicates with HOAT. HOAT coolants typically mix an OAT with a traditional inhibitor, usually silicates. Typically, OAT antifreeze contains an orange dye to differentiate it from the conventional glycol-based coolants (green or yellow), though some OAT products may contain a red or mauve dye. However, since 2018, they have moved on to G12EVO (TL 774-L) which no longer contains glycerol. To achieve interoperability between applications, neutral, non-proprietary or open standa...

When used in an automotive context, corrosion inhibitors are added to help protect vehicles' radiators, which often contain a range of electrochemically incompatible metals (aluminum, cast iron, copper, brass, solder, etc.). In addition to its potential clarity and transparency, it may help promote standardization across the industry. Adjusting is the final setting of balancing devices such as dampers and valves, adjusting fan speeds and pump impeller sizes, in addition to automatic control dev...

Testing is the use of specialized and calibrated instruments to measure temperatures, pressures, rotational speeds, electrical characteristics, velocities, and air and water quantities for an evaluation of equipment and system performance. While not necessary to be a TAB contractor, many contractors tend to hold professional air balancing certifications. The US industry standard that outlines the recommended qualifications for fire safety educators is NFPA 1035: Standard for Professional Qualif...

In most cases the fire department representative is regarded as the expert and is expected to present information in a manner that is appropriate for each age group. In the event of fire, plastic insulations made of EPS or XPS sometimes melt quickly in an uncontrolled manner and can produce smoke and toxic gases. Non-hazardous. Being fireproof, it will not smoke at all upon direct contact with flame, and is a two-hour firewall at a 3.5 in (89 mm) (or normal 2 in × 4 in (51 mm × 102 mm) stud wal...
