Making Your
Own Glass |
Lead highly
toxic; arsenic oxide extremely toxic; antimony oxide moderately toxic;
sodium cyanide extremely toxic |
Silica
toxic; lead highly toxic; arsenic oxide extremely toxic; antimony oxide
highly toxic; sodium cyanide extremely toxic |
Lead highly
toxic; arsenic oxide highly toxic; antimony oxide moderately toxic; sodium
cyanide moderately toxic |
Arsenic,
Antimony oxide carcinogenic; lime corrosive |
Use cullet
when possible; avoid lead, arsenic, antimony; don't use sodium cyanide;
use fume hood; keep antidote kit; use exhaust hood, respirator, gloves;
wet mop; don't eat or drink in work area |

Firing,
Melting, & Annealing |
|
Carbon
monoxide highly; nitrogen oxides, fluorine, sulfur oxides, chlorine, metal
fumes toxic |
|
Heat stress
diseases; thermal burns; infrared radiation; fires;ceramic fibers from
ovens carcinogenic |
Use local
exhaust ventilation, canopy hood; insulation made of firebrick; don't use
asbestos; take frequent breaks to cool body; treat heat rash w/lotions;
use reflecting shields, infrared-absorbing barriers; use infrared goggles
(shade #1.7-3) |

Working
Freeblown Glass |
|
Colorants
can release metal fumes, toxic gases |
Risk of
injury from broken glass |
Chronic lung
problems; requires a lot of strength |
Wear heavy
shoes, metal mesh safety gloves; add chemicals only under canopy hood; use
glass color bars to add colorants; protect against infrared; take frequent
breaks; don't do glassblowing if you don't have the strength |

Decorating
Glass |
Acids
corrosive |
Metal salts
haz.; acids corrosive; fluorine, chlorine, sulfur dioxide, nitrogen
dioxide haz. |
Metal salts
haz.; acids corrosive |
Zinc, iron,
copper fumes cause metal fume fever |
Use painting
& dipping, instead of spraying; spray metal salts and acid only under
canopy hood, w/ventilation & respirator; wear gloves, goggles, apron;
add acid slowly to water; skin/eye contact w/ammonia should be rinsed
thoroughly (eyes 15 minutes) |
| 6 |
Cutting
& Finishing Glass |
Ammonium
bifluoride highly toxic (corrosive) |
Glass
particles haz.; abrasives haz.; tin oxide slightly toxic; sand haz.;
hydrofluoric acid highly corrosive |
Cerium oxide
can damage eyes; hydrofluoric acid highly corrosive; ammonium bifluoride
highly toxic |
Broken glass
haz. to eyes;shocks; contaminated water |
Wear
goggles; install ground fault circuit interrupter; regularly clean water
reservoirs; clean w/bleach; don't use sand; make sure blasting machine
doesn't leak; wear blasting hood w/respirator; don't use hydrofluoric acid
(if so, use fume hood) |

|
Heat stress

Risk of
injury from broken glass |
Fire haz.
from torches; chronic lung problems; thermal burns |
Wear heavy
shoes, metal mesh safety gloves; add chemicals only under canopy hood; use
glass color bars to add colorants; protect against infrared; take frequent
breaks |
