A. Introduction

The glass cutter can be used to cut fused silica and glass.

This SOP should be read and understood prior to the commencement of relevant work and used to complement supervised practical familiarization with the various techniques described.


B. Hazard identification and personal protective equipment

B1. Hazards: Crushing, eye and body injury.

B2. Personnal protective equipment (PPE): Eye protection and/or face shield and glass-handling gloves must be used.


C. Procedures for safe use of the glass cutter

The following steps must be followed.

1. Only operate the cutter if you have been trained to use it.
2 . The glass cutter is to be used only after lectures have finished on weekdays. It may be used on weekends provided knowledgeable laboratory personnel have been alerted and at least one is in the general vicinity to provide assistance if necessary. 
3 . Check the blade and the machine before using. Do not use if the blade is broken.
4 . Set the water-cooling system; make sure that there is enough water to cool the blade.
5 . Always switch off the machine after each operation. 
6 . Remove any broken pieces of glass from the cutter’s water basin to avoid clogging the basin drain 
7 . Let accumulated water drain completely to avoid further rust damage.
8 . Remove the drainage hose from floor drain so that it is not a tripping hazard
9 . If the glass cutter becomes inoperable or another problem arises e.g. clogged basin or a broken cutting disc please notify one of the Subramanian research-group members.
10 . Sign the signup sheet after using the cutter.
