SCIENCE LAB SAFETY REINFORCEMENT AGREEMENT While all experiments in this manual are micro-scale or small-scale, which reduces most potential risks, unforeseen risks may still exist. The need to prevent injuries and accidents cannot be over-emphasized! Use of this lab manual and the LabPaq are expressly conditioned upon your agreeing to follow all safety precautions and accept full responsibility for your own actions. Thus, it is prudent to review the LabPaq’s basic safety rules and relevant safety precautions. You should study the safety section of the manual until you can honestly state the following: DB_I know that except for water, most solvents such as toluene, alcohols, acetone, ethers, ethyl acetate, etc. are highly flammable and should never be used near an open flame. DB_I know that the heat created when water is added to concentrated acids is sufficient to cause spattering. When preparing dilute acid solutions, I will always add the acid to the water (rather than the water to the acid) while slowly stirring the mixture. DB_I know it is wise to wear rubber gloves when handling acids and other dangerous chemicals that acid spills should be neutralized with sodium bicarbonate (baking soda), and that acid spilled on the skin or clothes should be washed off immediately with a lot of cold water. DB_I know that many chemicals produce toxic fumes and that cautious procedures should be used when smelling any chemical. When I wish to smell a chemical I will never hold it directly under my nose but instead will use my hand to waft vapors toward my nose. If I experiment at home I will keep a window or door open while performing experiments. DB_I will always handle glassware with respect and promptly replace any defective glassware because even a small crack can cause glass to break when heated. To avoid cuts and injuries, I will immediately clean up and properly dispose of any broken glassware. DB_I will avoid burns by testing glass and metal objects for heat before handling. I know that the preferred first aid for burns is to immediately hold the burned area under cold water for several minutes. DB_I know that serious accidents can occur if the wrong chemical is used in an experiment. I will always carefully read the label before removing any chemical from its container.

DB_I will avoid the possibility of contamination and accidents by never returning an unused chemical to its original container. To avoid waste I will try to pour out only the approximate amount of chemicals required. DB_I will select a work area that is inaccessible to children and pets while experiments are in progress. I will not leave experiments unattended and I will not leave my work area while chemical equipment is set up unless the room will be locked. DB_To avoid the potential for accidents I will clear my home-lab workspace of all non- laboratory items before setting up my lab equipment and chemical experiments. DB_Before beginning an experiment I will first read all directions and then assemble and organize all required equipment and supplies. DB_ I will wear approved safety glasses at all times while working on lab experiments involving chemicals, and if I ever spill any chemical on myself I will immediately flush the spill with a lot of water and then consult a doctor if required. DB_To protect myself from potential hazards I will wear long pants, a long-sleeved shirt, and enclosed shoes and I will tie up any loose hair, clothing, or other materials when performing chemical experiments. DB_I will never attempt an experiment until I fully understand it. If in doubt about any part of an experiment, I will first speak with my instructor before proceeding. _I will never eat, drink, or smoke while performing experiments. _After completing all experiments I will clean up my work area, store the lab equipment in a safe place that is inaccessible to children and pets, and wash my hands to remove any chemicals. DB_I will always conscientiously work in a reasonable and prudent manner so as to optimize my safety and the safety of others whenever and wherever I am involved with any type of chemical equipment or experimentation. Permission to utilize a LabPaq is contingent upon you agreeing to follow all prescribed safety procedures. Please review this document several times until you are certain you understand it and then sign the agreement below. Your instructor may require you to send him/her a copy. I am a responsible adult who has read, understood, and agree to fully abide by all safety precautions prescribed by my science lab manual for lab work and the use of LabPaqs. I recognize the inherent hazards potentially associated with science experimentation and I will always experiment in a safe and prudent manner. Thus, I unconditionally accept full and complete responsibility for any and all liability related to my purchase and/or use of a

science LabPaq or other any science products or materials provided by Hands-On Labs, Inc. (HOL). _______Deborah Boyanski___________________________________10/24/2023_________ _______________ Student’s Signature Date
