# Wha t ar e the Health Risk s with SPF Applic at ion
 Sensitiz at ion and asthma, a potentially life-thr eatening disease  Re spir ator y pr oblems and other br eathing difficulties

3  Skin and ey e irrit at ion  Other potential adver se health effects

# Wh y is Ven tila tion Import an t
 Airborne contaminants are gener ated during the application pr ocess  Va por s and mists gener ated during spr ay ing  Dus ts/particula tes gener ated during trimming /c ut ting /g rinding

4  Dus ts/particula tes gener ated during trimming /c ut ting /g rinding  Va por s also emitted during curing  Wo rker s and other s in the ar ea can br eath airborne contaminants or get them on the skin/ ey es  Pr operly designed ve nt ila tion can help r educe airborne contaminants  Po orly designed v entilation could mak e matter s wo rs e

# Fundamen ta ls of Ven tila tion **Tw o**  **Basic T**

**ypes of V en**  **tilation**  Gener al ex haust ve nt ila tion  Inside air is r emov ed fr om the r oom or ar ea and r eplaced with outside air

6  Commonly referr ed t o as dilution v en tilation  Local e xhaust ve nt ila tion  Exhaus t hood is located at the sour ce of contamination to captur e contaminant befor e it can mix with air in the r es t of the r oom  Re commended fo r contr olling haz ar dous airborne contaminants

# SPF Ven tila tion Challeng es
 Ea ch work site is differ en t  Po in t of application (the sour ce of airborne cont aminan ts) is constantly moving

7  One siz e fits all appr oach will not w ork  Need to under sta nd principles of ventilation to ensur e effectiv e design  The dr aft fact sheet fo cuses on k ey principles to enable applicator s

# Basic Ve nt ila tion Design Principles **Key Componen**  **ts of a V**

**en tilation**  **System**  Wo rk space to be ventilated  Exhaust syste m

8  Mak e up air Under sta nding how these components work together is a k ey to effectiv e design

# Es ta blish Air Flow Acr oss Spr ay ing Ar ea **Key Principles**   Flow acr oss the entir e work space  Dr aw contaminants awa y fr om work er s

9  Dr aw contaminants awa y fr om work er s **Re lat**  **ed Tips**  Avo id impr oper fa n placement  Place ex haust hood as close to application point as possible

# Es ta blish an Enclosur e t o Isola te C on ta minan ts **Key Principles**   Pr events migr at ion of cont aminan ts to other ar eas  Minimiz es the siz e of the ar ea to be e xhausted

11  Minimiz es the siz e of the ar ea to be e xhausted **Re lat**  **ed Tips**  Establish a neg at iv e pr essur e in the ar ea  Avo id short cir cuits  Seal off building HV

AC openings

# Dir ect Exhaus t t o a Safe Loc at ion **Key Principles**   Exhaust outdoor s awa y fr om people  Establish a contr ol z one to k eep people out Wa tc h out for building mak e up air int ak es

13  Wa tc h out for building mak e up air int ak es **Re lat**  **ed Tips**  Ins ta ll particula te filter s  Re moves particulate fr om e xhaus ted air  Pr otects fan  Fa n ma y need to be e xplosion pr oof...check with SPF manufactur er

# Ensur e Adequa te Ven tila tion Aft er Applic at ion
