This is from Larry Shapiro:
The Prospect Heights Fire District held training exercises at a vacant house located at 207 South Parkway during the week of June 22nd. I stopped by on Friday, June 26th, to capture some images. Below are a few photos along with a short video. You can view more pictures on my website: shapirophotography.net.
I found the training session to be quite informative and well-organized. The firefighters were practicing various techniques, including live fire scenarios, which gave a real sense of the intensity of their work. It was interesting to see how they worked together under simulated conditions.
Here are some highlights from the day:

[Image 3: A firefighter silhouetted against the smoke]
[Image 4: Firefighters making an entry into the structure]

[Image 6: Live fire training in progress]

STPP Industry Grade
Sodium Tripolyphosphate 94% or named : PENTA-SODIUM TRIPHOSPHATE, PENTASODIUM TRIPOLYPHOSPHATE,SODIUM TRIPHOSPHATE PENTABASIC,SODIUM TRIPOLYPHOSPHATE PENTABASIC.
GB/T 9983-2004
Chemical formula: na5p3o10
Molecular weight: 367.86
CAS No.: 7758-29-4
EINECS No.: 231-838-7
Sodium polyphosphate is white powder crystal with good fluidity. It is commonly known as pentasodium because its molecule (na5p3o10) has five sodium atoms. Sodium tripolyphosphate is easily soluble in water and its aqueous solution is alkaline, so most of it is used in synthetic detergents.
Sodium tripolyphosphate has the functions of chelation, suspension, dispersion, gelling, emulsification and pH buffer. It can be used as main additives of synthetic Detergent, industrial water softening agent, tanning pretanning agent, dyeing additives, organic synthesis catalyst, dispersant of pharmaceutical industry and food additives. In addition to exporting STPP, domestic STPP consumption is mainly concentrated in detergent industry, food, ceramics, etc.
