Laser Hazards and Cntrl Measures The fcus f the Hmewd Laser Safety Prgram will be t reduce the pssibility f harm by the expsure t the eye and skin f laser radiatin, r expsure t ther hazards assciated with lasers and laser systems during peratin, servicing, maintenance and strage when nt in use. Types f Hazards Laser irradiatin is nt the nly hazard that exists with lasers. When cnsidering the installatin f a laser the fllwing hazards shall be cnsidered as part f the installatin apprvals and SOP s. The list presented in Appendix A is illustrative and shuld nt be cnsidered exhaustive. JHU shall implement a hazard cntrl prgram that utilizes the hierarchy f cntrls detailed in Figure 1: Figure 1: Hierarchy f Cntrls frm LIA-Laser Safety Manual, 2007 (lia.rg) Substitutin -Substitutin is always the ptimal methd f cntrl. Eliminatin f a risk ttally ensures safety against that hazard. It is understd that risks cannt be eliminated, but they shuld never be greater than abslutely warranted (r than a level deemed acceptable). The lwest pwer lasers necessary shall be utilized in existing r planned installatins. If a higher pwer laser is selected because f planned future experiments, the SOPs shall be develped cnsidering thse hazards and experiments. As a substitute t direct viewing a laser beam within the NHZ, alternate means f viewing the beam during alignment shuld be cnsidered. Cnsideratins include: Charge Cupled Devices (CCDs) Web cameras Thermal imagers Flurescent papers and panels Dispsable targets Engineering Engineering cntrls are features and ther design characteristics f laser systems implemented t prevent the incidental ver expsure by blcking r preventing laser light frm escaping a defined path in an uncntrlled manner such that it culd cause injury t peple r damage equipment. Engineering cntrls shall be the first line f defense in preventing ver expsure t laser light. All engineering cntrls n the Hmewd campus shall be implemented using the best practices f the Standard except where alternate methds and/r materials cnfer an equivalent degree f risk reductin. LASER SAFETY MANUAL-REV1.DOCX Page 9 f 16

Persnal Prtectin Equipment (PPE) Eyewear is primarily cncerned with prtecting the retina as well as ther cular structures frm expsure t laser light. Laser glasses can prtect the lens f the eye frm ultravilet (UV) light, and bth the interir and exterir f the eye frm infrared (IR) expsure. Prperly selected eyewear will reduce the incident expsure t the eye t less than the Maximum Permissible Expsure (MPE) as defined by the Standard while maximizing Ttal Visible Light (TVL) transmissin. All eyewear used n the Hmewd Campus in cnjunctin with Class 3 and 4 lasers shall be reviewed and verified by the LSO. Fr details see Sectin 8 f the Standard. Other Class 4 (especially IR and UV) lasers may require ther PPE. The LSO shall verify that required PPE is present (see appendix A). Medical mnitring is required fr all ALU s f Class 4 lasers and is recmmended fr Class 3B lasers. This medical mnitring shall start with a retinal examinatin and visual acuity study prir t wrking with lasers. Upn leaving the university JHU students and emplyees shall be given a secnd study upn request. Administrative Cntrls It is recgnized that due t the nature f research wrk undertaken n the Hmewd Campus, it is nt pssible t implement engineering cntrls t design ut r remve all hazards. This is especially true where lasers must be aligned t ensure that an experiment is prperly set up. Training -All PLOs, ALOs, and LUs using systems cntaining cntrlled lasers shall receive training t ensure that they are fully cgnizant f the laser hazards they will face and what precautins they must take t ensure the safety f themselves and thers. Initial training shall be given prir t using the laser system with a refresher training being given nce per year fr class 4 lasers and every ther year fr class 3B lasers. Undergraduate students shall receive laser training when perating r using any lasers Class 3 r Class 4. There shall be specific training mdules tied t each class where the lasers are being used. SOP s - Prper training shall be supplemented with SOP s t ensure that ALO s take all necessary steps t ensure their wn safety and the safety f thers while aligning lasers r therwise wrking inside the NHZ. [See appendix B] SOP s shall anticipate the all knwn pssible uses f the laser system being described, including but nt limited t the fundamental emissins f the beam (frequency, pwer, rate), the specificatins f the NHZ, r engineering cntrls t be used in rder t minimize the need t resubmit the SOP fr review. Additinally SOP s shall be supplied t guide LU s t ensure that they can run experiments r ther peratins safely. ALU s and LU s shall immediately infrm the apprpriate PI and the LSO when they suspect that a SOP s has been vilated r when believe that an SOP is nt meeting its intended safety bjectives. Signage Signage has tw functins: Infrm spectatrs and ther casual users f a space f the existence f lasers. Act as a reminder t users f the space that lasers are present and what cnsideratins are necessary t ensure safety. All cntrlled laser installatins n the Hmewd campus shall be indicated with the apprpriate signage as recmmended by the Standard. Recrds The fllwing recrds shall be kept by JHU as nted fr the duratin indicated. LASER SAFETY MANUAL-REV1.DOCX Page 10 f 16

APPENDIX C LASER EMERGENCY RESPONSE PLAN In the event f a laser emergency /accident it is imprtant t respnd prmptly and apprpriately. Incidents with cntinuing hazard (fire, explsin, gas leak, high vltage, etc.) 1. Shut dwn the laser and assciate equipment using apprpriate emergency prcedures as established in the SOP. 2. Ntify thers in the immediate area f the hazard. 3. Evacuate the immediate hazard area. 4. In case f fire r explsin sund the nearest fire / emergency alarm as yu exit the building 5. Cntinue yur evacuatin t a safe area utside the building 6. Frm a safe lcatin Cntact Security (410-516-7777) using yur cell phne r emergency statin. When talking t security prvide the fllwing details cncisely and explicitly: a. Lcatin f incident / accident b. What is happening r happened. c. If there were thers in the area f the incident infrm security wh the peple are and their situatin, especially if yu suspect that they may be injured. d. Prvide campus security with the name f the respnsible Lab Manager and / r Principal investigatr e. Agree upn a lcatin t meet security 7. Wait fr the security and the emergency respnders t arrive. DO NOT leave the general scene. Be prepared t prvide details as t what was happening when yu left the lcatin f the incident. 8. Once the situatin is stabilized a. Cntact bth yur PI and Lab Manager b. Be prepared t prepare a detailed reprt n the incident Injury incidents that present NO cntinuing hazard t yu 1. Shut dwn the laser and assciate equipment using apprpriate emergency prcedures as established in the SOP 2. Stabilize the injured persn using apprpriate emergency first aid prcedures. 3.
