+# Introduction to PSAS Risk Management
+
+- PSAS has never had a serious accident.
+- PSAS is the only amateur group we know of that has safety SOPs and contingency plans. These plans have been reviewed and highly praised by TRA safety personnel.
+- PSAS falls all TRA safety regulations and uses experience TRA L3 personnel for all launches.
+- PSAS takes risk seriously and works with an engineering mentality to mitigate known risks: example is the launch tower computer safety interlock system.
+
+# Risk Analysis
+
+- Team meetings
+ - Nothing can go wrong
+- Transportation to and from events
+ - Car driving [Catastrophic and Unlikely] = H
+- Field testing
+ - Unexpected recovery system actuation: [Marginal and Unlikey] = L
+ - Someone falls off launch tower: [Marginal and Unlikely] = L
+ - Launch tower falls on someone: [Marginal and Unlikely] = L
+ - Battery explosion: [Marginal and Unlikely] = L
+- Launch
+ - Includes all field testing risks
+ - Motor and igniter
+ - Fuel fire: [Critical and Unlikely] = L
+ - Explosion on pad: [Catastrophic and Unlikely] = M
+ - Premature launch: [Catastrophic and Unlikely] = M
+ - Recovery system failure
+ - Rocket shreds and falls: [Critical and Seldom] = M
+ - Rocket lawn darts: [Catastrophic and Unlikely] = M
+
+# Risk Mitigation
+
+## High
+
+- Car driving [Catastrophic and Unlikely]
+ - All students being driven sign waivers.
+ - All drivers sign waivers and become approved SALP drivers.
+
+## Medium
+
+- Premature launch/explosion on pad: [Catastrophic and Unlikely] = M
+ - All TRA safety protocols followed.
+ - Only TRA L0 and over allowed in launch prep area.
+ - Only TRA L3 allowed to handle and prepare motor.
+ - Multiple safety interlocks and PSAS SOPs make premature launch nearly impossible.
+ - Last safety interlock is 100 ft away.
+ - All personnel > 1,500 ft away during countdown and launch.
+ - PSAS SOPs exist for this contingency.
+
+- Rocket shreds and falls: [Critical and Seldom] = M
+ - All personnel > 1,500 ft away during launch.
+ - Airframe has been launched multiple times and the design has been reviewed by TRA L3 personnel.
+ - Rocket designed to "shred" in small, lightweight parts.
+ - PSAS SOPs exist for this contingency.
+
+- Rocket lawn darts: [Catastrophic and Unlikely] = M
+ - All TRA safety design protocols followed, including redundant recovery devices.
+ - Recovery system has been thouroughly tested and reviewed by TRA L3 personnel.
+ - All personnel > 1,500 ft away during launch.
+ - Rocket is tracked and position broadcast via radio during flight.
+ - PSAS SOPs exist for this contingency.
+
+## Low
+
+- Fuel fire: [Critical and Unlikely] = L
+ - All TRA safety protocols are followed.
+ - Fire safety equipment is present at all launches.
+ - Fuel is handled only by TRA L3 personnel.
+ - Note: fuel is *very* difficult to start on fire.
+ - PSAS SOPs exist for this contingency.
+
+- Unexpected recovery system actuation: [Marginal and Unlikey] = L
+ - All TRA safety protocols are followed.
+ - Recovery system pyrotechnics are extremely weak and are safeted until armed for flight on pad.
+
+- Someone falls off launch tower: [Marginal and Unlikely] = L
+ - Climbers are roped in to tower when above 10 ft.
+ - Climbers are kept below 20 ft.
+
+- Launch tower falls on someone: [Marginal and Unlikely] = L
+ - Launch tower is a standard radio tower that is secured with apropriate safety rigging.
+ - SOPs are followed for erection.
+ - Launch tower is a minimum size and weight for application.
+
+- Battery explosion: [Marginal and Unlikely] = L
+ - All batteries have fuses and electrical safety mechanisms (circuit breaker).
+ - All batteries are handled by experienced personnel.
+ - All electrical systems have been design reviewed by experienced, qualified electrical engineers for performance and safety.
