It is extremely important to be well informed about safety when learning and practicing the art of glass blowing. To become an accomplished scientific glassblower in a research environment, years of experience are required, as well as exposure to the many fields of science. Glassblowers usually spend ten or more years working in a multi-science environment before being considered “Master Glassblowers”. In the United States, glassblowers learn their craft through an apprenticeship.
Always wear appropriate protective clothing, equipment, and very importantly, safety goggles. Burns and cuts are always a possibility, sometimes severe enough to result in serious injuries and death. Always inspect the entire work area, most importantly the gas supply system, and confirm safe working conditions at all times. Have someone close by at all times to offer assistance if necessary.
Attempt repair to scientific glassware with caution. If the glassware was broken in use, or has been used in the laboratory at some point, it most likely has chemical residue in or on it. Do not make any repairs until the glass has been thoroughly cleaned. As you heat the glass, and out gassing that occurs is deposited directly into your mouth by the blow hose assembly, so make sure the glass has been properly cleaned.
Also, broken glass and leftover pieces are never to be left in the regular trash, as this may cause serious injury to waste handlers. Sharp containers must be used. Glass blowing facilities must conform to all local, state and federal regulations for personal, property and environmental protection.
