Emergency Response
3D Printing Emergencies
Burns from Hot Surface
Touching the hot surface, including the hot nozzle, hot end, Heated Bed, Print Sheet, and uncured filament, will burn
your skin. Should you be burnt:
(1) Get yourself away from the heat source.
(2) Immediately rinse your burnt area with cool running water.
(3) Remove any clothing or jewelry near your burnt area.
(4) Use painkillers if necessary.
(5) Cover the burn with a clean, dry bandage.
(6) Should you suffer from severe burn, seek medical help immediately.
Inhalation of Fumes and Granules
Printing with certain filaments will emit fumes or produce granules, which may irritate your respiratory system.
Generally, we recommend you use safety addons and wear protective masks when printing.
Should respiratory irritation occur, immediately expose the victim to fresh air and seek medical help immediately.
Laser Emergencies
Eye Injury from Laser
Should your eyes be exposed to direct or scattered laser beams, take the following steps as an emergency response:
(1) Grab a nearby thick and opaque object to block the laser beam to prevent further exposure to laser.
(2) Shut down the laser engraving and cutting machine immediately.
(3) If an eye injury is suspected, medical examination by a qualied specialist needs to be carried out as soon as
possible.
(4) If an eye injury is apparent, call the local hospital for emergency help.
If a medical emergency occurs in which the extent or nature of the injury precludes you from further
actions, sit down on the floor and yell for help. Warn any respondent of laser danger and ask them to
turn off the laser engraving and cutting machine before sending you to the hospital.

Skin Injury from Laser
Lasers can harm the skin via photochemical or thermal burns, which can be treated as could any other burn. Take the
following steps as an emergency response:
(1) If it is a major burn, call for emergency medical care before you take the subsequent steps.
(2) Remove any clothing or jewellery that’s near the burnt area of skin, but do not move anything that’s stuck to the
skin.
(3) Hold the burn under cool or lukewarm running water until the pain subsides. Use cool, wet compresses if
running water isn’t available.
(4) After the burned area has been cooled, use painkillers such as paracetamol or ibuprofen to treat any pain.
(5) Loosely bandage the burn. Use a sterile, non-adhesive bandage or clean cloth.
Exposure to Gases or Fumes
The heating which occurs during laser cutting or engraving can cause charring, pyrolysis, and even combustion of the
material being worked on and generate gases or fumes.
• Airway Irritation
Gases and fumes may irritate the airways and potentially be extremely dangerous. Should airway irritation occur,
take the following steps as an emergency response:
(1) Expose the casualty to fresh air.
(2) Call for medical help.
(3) If the person is unresponsive, not breathing, or not breathing normally, perform CPR until the person begins
breathing or emergency help arrives.
• Eye Irritation
Being exposed to gases or fumes may cause the eyes to become red and watery, and induce a grainy feeling.
Should eye irritation occur, take the following steps as an emergency response:
(1) Rinse the affected eyes with room temperature water for 10 to 20 minutes to relieve symptoms. Sterile water
or sterile normal saline solution (0.9%) from sealed disposable containers can be used. Press the eyelids wide
open and keep them apart while rinsing.
(2) Transfer the casualty to the hospital as soon as possible for an eye examination and further treatment.
• Asthma Attacks
Gases or fumes may trigger asthma in a person with asthma history. Should an asthma attack occur, take the
following steps as an emergency response:
(1) Sit the person upright.
(2) Give 4 puffs of blue reliever puffer. Ensure you shake the puffer, put 1 puff into a spacer at a time, and get the
person to take 4 breaths of each puff through the spacer. Remember: shake, 1 puff, 4 breaths.
If you don’t have a spacer, simply give the person 4 puffs of their reliever directly into their mouth. Repeat this
until the person has taken 4 puffs.
(3) Wait 4 minutes. If there is no improvement, give 4 more separate puffs as in Step (2).
(4) Keep giving reliever. Give 4 puffs every 4 minutes until the ambulance arrives.
Fire
Laser engraving and cutting can present a significant fire hazard due to the extremely high temperature caused by the
laser beam. Should a fire occur, take the following steps as an emergency response:
Safety Guidelines - Emergency Response

User Manual | 11
Safety Guidelines - Labels on Your Snapmaker
(1) If the re is small in size (no larger than a small trash can), you can use an extinguisher to put it out. Remember
to cut electrical power before dousing the ame.
(2) If the re is large, do not attempt to ght it yourself. Call for help immediately by pulling the nearest alarm.
(3) Move quickly to the nearest accessible exit. Notify, and assist others to evacuate along the way. Do not use the
elevators.
(4) Contain the re and the smoke by closing all doors leading into and surrounding the re area. Do not lock them.
(5) After a total and immediate evacuation, call medical attention for the casualty.
CNC Emergencies
Injury from Sharp Objects
Should you get injured from sharp objects, follow these first aid steps:
(1) Stop the bleeding. Apply pressure to the wound with a clean cloth for a few minutes until the bleeding stops. If
the bleeding won’t stop or other tissues are severely injured, seek medical help immediately.
(2) Remove any dirt and debris. Use sterilized tweezers to remove dirt and debris around the wound. If the debris
penetrates deep into your skin, seek medical help immediately.
(3) Clean. Gently rinse the wound, and wipe away the residual water using a clean cloth.
(4) Disinfect. Apply an antiseptic cream on the wound to prevent infection. If the wound is infected, seek medical
help immediately.
(5) Band up. Use a bandage to protect the wound from further exposure to dirt and bacteria.
Note that any injuries to the vulnerable parts, like faces, eyes, and arteries, requires immediate medical treatment.
Inhalation of Dirt and Sawdust
CNC carving will produce dust and sawdust, which may irritate your respiratory system. Generally, we recommend
you use safety addons and wear protective masks when carving. Should respiratory irritation occur, immediately
expose the victim to fresh air and seek medical help.
Inhalation of Scorched Smell
Sometimes, CNC carving may emit a scorched smell, which may irritate your respiratory system. Should respiratory
irritation occur, immediately expose the victim to fresh air and seek medical help.
