Technology Education Part 1 General Lab Safety Purpose

Technology Education Part 1 General Lab Safety

Purpose Of Lesson • Basic safety for everyday life • Basic shop safety • How to find & follow safety information on tools & equipment

In This Lesson: 1. 2. 3. 4. 5. 6. 7. Class/Shop Policies & Procedures Proper shop behavior Proper dress Personal Protective Equipment (PPE) First Aid Blood Bourne Pathogens Material Safety Data Sheets (MSDS)

st 1 Rule! • DO NOT RELY on the protective gear to keep you safe! • Example: Wearing your seat belt that does not make you invincible & 100% safe from injury to yourself &/or make it impossible for you to hurt others!

Equipment • Never use equipment that you are not trained to use & have passed the safety test with a 100%. • Do not ask the instructor to use equipment you are not trained to use & have passed the safety test with a 100%.

• If your not using a tool you should not be handling it &/or playing with it! • Get permission to use any tool or equipment • Only one student at a time use a tool

• You may not use tools unless the instructor is present. Unfortunately, I have to say these: • Pease don’t throw away tools! • Please don’t throw away large scraps, they are often not scraps, & we can use them. Example: 8 foot $33 oak board, cut off 2 feet to use on project, then thrown the remaining 6 feet of board away. Yep, kiddos have done this ; ) Please don’t do this…

Report any unsafe conditions to instructor IMMEDIATELY! • One of the 20 -30 students in the classroom might be the first to notice that something has malfunctioned &/or is or has gone wrong before the instructor does! Tell me immediately! Picture Above: is a Cracking Band Saw Blade will make a clicking noise when in use. When it breaks 14 feet long saw blade can come flying out!

Emergency Shutoff Switches • Each machine has an on/off switch. • Also, many are equipped with an emergency shutoff switch. • • Additionally, the classroom & the shop have whole room emergency power shutoff switches. In an emergency you should shut off the power & shut off the emergency shut off switches as fast as possible.

Behaviors • • Walk! NEVER RUN! Stay on a Dry Floor. No horseplay. Do not distract others while working with machinery &/or tools. • Do not throw &/or toss anything in the classroom &/or shop. • Only one person per machine!!!

At the End of Each Hour • 5 minutes before the end of class students need to stop working. • Put up their projects • You need to clean up your work area. • & Put away any tools in their proper place.

Dress Correctly • No open toed shoes • No necklaces, ties, lanyards, long loose hair, hoodie strings, &/or etc. • Long sleeves rolled up securely.

Personal Protective Equipment PPE • • Safety glasses Face shields Gloves Aprons Ear plugs Respirator &/or etc.

Safety Glasses • Safety glasses are required in the shop. • Top: Normal safety glasses. • Bottom: Safety glasses designed to go over prescription eye glasses.

Safety Glasses Requirements • Safety glasses are required to be made of polycarbonate. • Must have side shield &/or be of a wrap around design. • If prescriptions glasses are poly side guards can be purchased. • I only supply the kind of glasses that go over prescription eye wear.

Goggles &/or Face Shield • Face Shields are better &/or required when it is known that debris will be flying through the air. • Safety goggles can be even safer & better.

Gloves • I do not purchase latex, too many people allergic, some people have life threatening reactions to them, & solvent dissolve them. • Nitrile is safe & it can stand up to many of the solvents we use. • We also have thick chemical gloves for use with caustics &/or acids. • In the shop we use leather gloves. To prevent wood splinters &/or burns.

Hard Hats • We will seldom need these in class / woodshop. • They are needed whenever there is a risk of falling debris. • On a construction site &/or in a manufacturing plant they are required!

Aprons, Respirators, & Ear Plugs • Aprons – Keep your clothing from getting messed up & have handy pockets. • Masks – can be used when there is a danger of particulate matter in the air. • Ear Plugs – Can be used when loud machinery is being used. Example: CNC machine cutting metal parts can be extremely loud!

Exhaust & Dust Collection Systems • Exhaust Systems – We have exhaust system that evacuates 275 cubic feet of air & fumes per minute to the outside of the building. • Dust Collection System – We have a very large industrial HEPA dust collection system that is pre-plumbed to every large shop tool & also has external hoses for use with smaller tools. Air coming out of this collector is cleaner than the air outside. Therefore, it keeps our lungs clean & it also helps keep the shop clean!

Sanitation • You are not required to purchase / have your own safety glasses & etc. but you may bring your own. • We have classroom sets of PPE, & sanitation supplies: UV Sterilization Cabinet, lens wipes, hand sanitizer, sink with soap & water, & etc.

First Aid • If you HAVE a preexisting scrape, small cut, &/or etc. I & pretty much every other teacher has first aid materials you may use to treat yourself. • If the instructor provides any first aid to student an report must be filed. • We, also have a school nurse that is almost always on campus.

First Aid • If you treat yourself for anything, instructor needs to be made aware of that as well. • If you have a scrape, a nosebleed, &/or etc. & there is blood in the trash can must be labeled. • & any blood, on any surface must be cleaned up only by the janitorial staff!

How to Handle Blood • Blood Borne Pathogens • AIDS, Hepatitis, & dozens of others • Consider any bodily fluid as though it is contaminated. • Do Not Touch • Do Not Handle

How to Handle Blood • Use Gloves • Dispose of in proper way • If serious – Fill out accident report • Mark Trash & notify Janitorial

Eye Wash Station • Eye Wash Station is for an emergency where particulate mater &/or chemical are in someone's eyes. • It’s not a water fountain, & we do have a drinking water fountain in class for that.

MSDS • MSDS stands for Material Safety Data Sheets • Also known as SDS Safety Data Sheets • They Contain the: The shipping, storage, disposal, safety & the emergency first aid directions for each of the chemicals used in that facility.

MSDS • All chemicals that you work with at school have an MSDS on file. The MSDS provides information about a chemical's toxicity, health hazards, physical properties, fire, and reactivity data—including storage, spill, and handling precautions. Please note, that some chemicals may display the revised Safety Data Sheets (SDS). Many of sections of the SDS are comparable to those on the MSDS. For example, first aid information will still be found in Section 4 of the SDS.
