Why must we all know Safety?

•  This isn’t a Manufacturing class. Why do I need to know Safety? – Because as future Architects, Engineers,

Designers, Chefs, etc., YOU need to know how to stay safe on the job site.

– You need to know your rights and responsibilities as Employees and/or Employer.


Paper Cutter

•  Never remove the guard from the paper cutter or any tool!

•  Keep fingers AWAY from the cutter path.

•  Only cut paper products on it.


Hobby/X-acto Knife

•  Never throw an X-acto knife. •  Only carry them when they have a safety

cap on them. •  Only use sharp blades. Wrap dull blades

in paper before you throw them away. •  Always cut away from yourself or others. •  Use a cutting pad whenever possible to protect

surfaces.


Scissors

•  Never run when carrying scissors.

•  Carry scissors with pointed end facing down.

•  Always cut away from yourself and others.


Hot Glue Gun

•  Its called a HOT glue gun for a reason, the glue can and will burn you!

•  Only put in it the correct size plastic glue sticks.

•  Let it cool completely before touching the metal tip or glue.


Poison

•  Keep the Poison Help yuck face sticker near your phone and/or on poisonous items.

•  Keep even potentially poisonous items locked up secure and out of sight.

•  Wash your hands after handling anything that could even be poisonous.


HAZMAT

•  Hazardous Materials like paint thinner or finger nail polish remover should never be thrown down the drain. It needs to go to proper collection site, just like used auto oil.

•  Wash your hands after handling HAZMATS or any material that you think could be hazardous. Better safe than sorry.


Wash Hands

•  You should wash your hands with soap for at least 20 seconds and then rinse with water and dry with a towel.

•  HINT: Sing the “Alphabet Song” - by the time you are done singing it will be 20 seconds.


Fire

•  Know your fire route out of every room or building.

•  If there is a fire, get everyone out. •  Once everyone is out, call 911. •  If it’s a small fire, attempt to put it out with

the appropriate fire extinguisher.


Fire

•  Know where the fire extinguisher is before there is a fire.

•  Follow “PASS” procedures when using it.

– Pull out the pin;

– Aim the nozzle at the base of the fire;

– Squeeze the handle; you only have approximately 30 seconds of spray;

– Sweep back and forth as you spray. Copyright © Texas Education Agency, 2012. All rights reserved.

Safety Colors

•  Red = Fire •  Orange = Dangerous •  Yellow = Caution or Slow Down •  Blue= Don’t move it or its being

repaired •  Purple = Radiation concerns •  White and/or Black = Traffic flow


Drafting Tools

•  This is a T-square. •  We use it to keep paper lined up.

•  It is NOT a sword or pretend gun.


Drafting Tools

•  This is a measuring scale. •  We use it to draw to precise

measurements and/or to scale.

•  It is NOT used as a pretend sword or drum sticks.


Drafting Tools

•  This is a divider. •  We use it to transfer measurements.

•  It is NOT used to poke holes in paper or to draw blood from people.


Drafting Tools

•  This is a Bow Compass. •  We use it to draw precise circles and arcs.

•  We do NOT use it to poke holes in paper or our classmates.


Drafting Tools

•  These are examples of drafting templates.

•  We use them to draw shapes quickly and correctly.

•  We do NOT use them to twirl on our fingers or to hit classmates with.


Drafting Tools

•  These are the 30/60 and 45 triangles.

•  We use them to draw straight lines and accurate angles.

•  We do NOT use them as throwing stars or to hit our classmates with.


General

•  If you spill something, clean it up ASAP. •  Use only a brush to clean off tables. •  Keep aisles clear of trash, tools, etc. •  Keep drawers and cabinets closed. •  Report immediately any accident no matter

how small. Yes, even paper cuts.


General

•  If a tool has become dull or isn’t working properly, let your teacher know ASAP.

•  Make sure your hands and work area are DRY before you use electrical equipment.

•  If a cord is frayed or damaged, do NOT use it – report it.

•  Always unplug equipment via the plug only.


General

•  Know where cords are at all times to avoid tripping.

•  You can tape down Ethernet cords only. •  NEVER tape down electrical cords as this

can cause them to heat up and catch on FIRE!


General

•  Only use tools like the paper cutter, hot glue, etc., when your teacher is present.

•  Always ask permission to use a tool before you actually use it.

•  If you aren’t sure how to use something, ASK!

•  Return tools to where they belong, not necessarily where you got it.


General

•  When lifting things, lift with your legs NOT your back.

•  Get help to lift really heavy or bulky things. •  Only use things like spray paint in a well

ventilated area. Store them in the fire resistant cabinet only. Store rags with chemical on them in a flame proof container.


ANSI

•  American National Standards Institute •  www.ansi.org

•  Their mission is: To enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards and conformity assessment systems, and safeguarding their integrity.


OSHA

•  Occupational Safety and Health Admin. •  www.osha.giv

•  Their mission is: With the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety and Health Administration (OSHA) to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.


MSDS

•  Material Safety Data Sheets

•  A material safety data sheet (MSDS) is a form with data regarding the properties of a particular substance. An important component of product stewardship and workplace safety, it is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures. MSDS formats can vary from source to source within a country depending on national requirements.


NFPA

•  National Fire Protection Association •  http://www.nfpa.org/ •  The mission of the international nonprofit

NFPA, established in 1896, is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus

codes and standards, research, training, and education.


NFPA - Red

•  Red = Fire Hazard –  0 – Will not burn –  1 – Must be preheated for

ignition; flashpoint above 200°F (93°C)

–  2 – Must be moderately heated for ignition, flashpoint above 100°F (38°C)

–  3 – Ignition may occur under most ambient conditions, flashpoint below 100°F (38°C)

–  4 – Extremely flammable and will readily disperse through air under standard conditions, flashpoint below 73°F (23°C)


NFPA - Blue

•  Blue = Health Hazard –  0 – Hazard no greater than

ordinary material –  1 – May cause irritation; minimal

residual injury –  2 – Intense or prolonged

exposure may cause incapacitation; residual injury may occur if not treated

–  3 – Exposure could cause serious injury even if treated

–  4 – Exposure may cause death Copyright © Texas Education Agency, 2012. All rights reserved.

NFPA - Yellow

•  Yellow = Reactivity Hazard –  0 – Stable –  1 – May become unstable at elevated

temperatures and pressures, may be mildly water reactive

–  2 – Unstable; may undergo violent decomposition, but will not detonate. May form explosive mixtures with water

–  3 – Detonates with strong ignition source

–  4 – Readily detonates Copyright © Texas Education Agency, 2012. All rights reserved.

NFPA – White &/or Black

•  White – Special Hazard –  - Reacts to water, do

not use around water! – Acid – ALK- Alkaline – COR – Corrosive – SA – Simple Asphyxiates –  - Radiation


Fire Symbols

•  The types mean it is SAFE to use on: – Type A = Trash,

Wood, Paper – Type B =

Flammable Liquids – Type C = Electrical

Fire


Personal Protection Equipment (PPE) Symbols

•  Wear protective clothing

•  Wear protective gloves

•  Wear protective boots

•  Wear protective breathing mask

•  Wear safety glasses, goggles, &/or face

shield. •  First aid

supplies are in here!


Caution Safety Symbols •  These are just 9 of the

most common caution symbols, there are many more: –  Explosions

–  Electricity

–  Bio Hazard

–  Hand Injuries

–  Radiation

–  Heat/Thermal

–  Cold

–  Fire

–  Slippery


100% Rule

•  Why do I have to pass the 50 questions test with 100%?

•  Because that means you will still have every finger, toe, etc., safe. 90% means it’s okay to lose 1 finger, 95% = part of a finger, etc….
