Welcome to Unit 6
In this unit, you will learn about:
•Potential effects of exposure to B-side ingredients in two-component low pressure spray polyurethane foam (SPF)
![Page 4: Unit 6: Potential Effects of Exposure to the B-side Two-Component Low Pressure](https://reader035.fdocuments.net/reader035/viewer/2022062517/568134bc550346895d9bdd39/html5/thumbnails/4.jpg)
B-side Ingredients
The B-side is a blend of different chemicals with the main ingredient being polyol and various additives including:•Catalysts•Blowing agents•Fire retardants•Surfactants
Potential health effects from exposure to additives can vary.
![Page 5: Unit 6: Potential Effects of Exposure to the B-side Two-Component Low Pressure](https://reader035.fdocuments.net/reader035/viewer/2022062517/568134bc550346895d9bdd39/html5/thumbnails/5.jpg)
Exposure Effects - Polyol
There is a low potential for adverse effects due to exposure to polyol by inhalation, skin or eye contact.

Skin Contact Effects - CatalystsCatalysts in the B-side may cause skin irritation including:
•Reddening
•Itching
•Swelling
•Possible allergic reaction

Eye Contact Effects - CatalystsCatalysts in the B-side can cause eye irritation including:
•Reddening
•Tearing
•Swelling
•Burning
•Temporary condition of impaired vision known as “Blue Haze” or “Halovision”

Inhalation Exposure Effects -Catalysts
Catalysts in the B-side may cause respiratory irritation including:
•Coughing
•Sore throat
•Runny nose
![Page 9: Unit 6: Potential Effects of Exposure to the B-side Two-Component Low Pressure](https://reader035.fdocuments.net/reader035/viewer/2022062517/568134bc550346895d9bdd39/html5/thumbnails/9.jpg)
Blowing Agents
In two-component low pressure spray polyurethane foam, blowing agents help expand the foam cells.
There is low potential for adverse effects from exposure to low pressure SPF blowing agents by inhalation, skin or eye contact.

Skin and Eye Contact Effects - Blowing AgentsSkin and eye contact with blowing agents can be slightly irritating.

Exposure Effects - Fire Retardants
Possible effects of exposure to fire retardants in the B-side include:
•Respiratory irritation – coughing, sore throat, or a runny nose
•Skin irritation
•Eye contact is not usually irritating
