Class Materials & Supplies

Academic Materials:

• Notebook or binder for keeping organized papers, assignments, references, and notes.

• Scientific or Graphing Calculator. 

Laboratory Supply:

• Students are asked to support the hygienic and safe working conditions of a laboratory by bringing in 1-2 rolls of paper towels.

• Goggles are supplied for students, but you may purchase your own splash googles that meet ANSI-Z87.1 criteria. Safety glasses or goggles that do not meet ANSI-Z87.1 will not be accepted and students will be required to wear the provided pairs. The instructor reserves the right to approve or deny the use of any safety equipment brought in. Goggles will be maintained in a sanitary condition to ensure proper safety.

A message on using proper eye protection.

All safety goggles need to comply with ANSI 87.1. Only safety goggles marked with ―Z87.1‖ should be purchased; the ―Z87.1‖ mark will appear on the frame or the lens.

Eye protection is required for (but not limited to) the following instances: 

 When chemicals, glassware, or heating sources are being used  When working with materials or equipment under stress, pressure, or force that might cause fragmentation or flying particles  When an activity generates projectiles, uses elastic materials under stress (e.g., springs, wires, rubber, glass), or causes collisions  When dust or fumes are present (eye protection reduces the dust or fumes reaching the eye)  When using preserved specimens 

 Eye protection is a must in any laboratory activity in biology, chemistry, or physics. Effective eye protection must include adequate instruction on the hazards of the particular activity and the precautions to be taken to reduce the risk of injury.

 Ordinary spectacles or safety glasses, with side shields or without side shields, do not provide adequate protection for laboratory activities. 

 Only safety goggles provide the level of protection needed for your laboratory activities. A safety goggle snugly fits the face surrounding the eyes; the goggle should have a soft, pliable flange that seals around the eyes snugly to protect the eye from a variety of hazards. 

 There are two major types of safety goggles. Safety goggles can be designed as chemical splash goggles and/or impact goggles. 

 Impact goggles are generally directly vented and appropriate for flying particles, fragmented materials, projectiles, elastic materials, and collision activities.  

• Chemical-splash goggles, like impact goggles, fit the face surrounding the eyes snugly. The soft, pliable flange seals around the eye. Because goggles need ventilation to reduce fogging, chemical-splash goggles are required to have hoods or caps over the vent openings to prevent splashes from entering the goggle and causing injury to the eye. The system of hoods or caps therefore prevents chemical splashes from entering the goggle. This type of goggle is indirectly vented. 

 Chemical-splash goggles should be the standard for eye protection when chemicals, glassware, a heating source, or preserved specimens are being used.  Since I am not certain what “in-person” schooling will look like at this time, I recommend obtaining a pair of goggles, and if you are concerned we will be moving to online only learning, you can consider getting a pair that you may return for a refund.
