The regulation prohibits picking up contaminated broken glass with hands and requires the use of mechanical tools for cleanup.
   29 CFR § 1910.1030(d): “Broken glassware which may be contaminated shall not be picked up directly with the hands. It shall be cleaned up using mechanical means, such as a brush and dust pan, tongs, or forceps.”
5. A nurse aide initially declines the hepatitis B vaccination offered by their employer but decides six months later that they wish to receive it. What is the employer's obligation regarding this request?The employer must provide the vaccination at that time. The standard requires employers to make the vaccine available whenever an employee decides to accept it, even if they previously declined.
   29 CFR § 1910.1030(f): “If the employee initially declines hepatitis B vaccination but at a later date while still covered under the standard decides to accept the vaccination, the employer shall make available hepatitis B vaccination at that time.”
