2017- 2018 NASA Student Launch
Hazard Communication
Purpose
• You have a Right to Know about the hazardous materials used in your work area and the potential effects of these materials upon your health and safety.
• Meet intent of requirement contained in NASA SL Handbook, Proposal/ Statement of Work, Safety, para. 1.2– Describe the plan for briefing students on hazard recognition and
accident avoidance, and conducting pre-launch briefings.
Agenda

Hazard Ratings
Physical Hazards
• Inhalation– Soldering– Sanding– Cutting
• Machining, handsaws, etc.
• Burns– Chemical Use– Soldering process– Miscellaneous
• Ignitors, etc.
• Noise
Physical Hazards
• Machine Shop
– Hazards
• Machines, chemicals, noise, etc.
– Follow established machine shop rules
• Motorsports Lab
– Small Work Area, many external projects
• Noise, hand tools. Etc.
Physical Hazards
• Explosives
– High Powered Rocket Motors
– Smaller Rocket Motors
– Igniters
– Gunpowder
Electro Static Discharge
• Electrical Components
– Ground yourself before handling
– Handle from outer edges
– Avoid contact with connections
Electrically Primed Components
• Explosive components susceptible to initiation through static discharge
– Igniters
– Electric matches
• Ground yourself prior to handling
• Ground yourself frequently during handling
Lithium Polymer Batteries
• Volatile when punctured
• Over-discharging causes permanent damage
– Damage is internal
– Potential fire when recharged
• Inspect:
– Prior to and after charging
– Before and after use
Protective Measures
• Proper PPE
– Chemicals
• Outlined in MSDS
– Machine Shop
• Safety Glasses
• Closed toe shoes
– Motorsports Lab
• Closed toe shoes
• Safety Glasses, as applicable
Protective Measures
• Situational Awareness
– Be aware of your surroundings at all times
• Who is nearby, what is being worked on, etc.
– Focus on the task at hand
Finally…
• Safety is paramount
• Ask questions if you need to
• Be mindful
• Do not accomplish tasks for which you are not trained
– Or seek the training required
• Wear your PPE
