Department of Chemical & Materials Engineering ESP# _____ - _____ - _____Experiment Safety Plan

An Experiment Safety Plan (ESP) is required for every experiment conducted within the Department, including those experiments performed by Department Employees/Students at a location away from Jett Hall. The purpose of the ESP is to assure the safety of all by identifying the safest possible methods to conduct an experiment. By signing below the individual(s) conducting the experiment, Chemical Hygiene Officer (CHO), and the faculty advisor acknowledge responsibility for the following requirements.

1) Appropriate Personal Protective Equipment (PPE) must always be worn while in the lab (as described in the ESP). The minimum required PPE to enter a research/teaching lab in Jett Hall is (1) long pants, (2) closed toe shoes, (3) lab coat or long sleeve shirt, and (4) safety glasses with side shields.

2) For safety reasons, no researcher is permitted to work alone in the lab at any time. Because the labs are open 24/7, there may be occasions (such as a late night or over weekends) when there are no other people working in the lab. If you plan to work during a time when the lab might be expected to be empty, please plan ahead and coordinate your work schedule with another lab member.

3) Training must be completed prior to working the experiment in the lab. The minimum required training to enter the lab can be completed through EH&S and includes the following courses: (1) Employee & HAZCOM Safety, (2) Lab Standard, (3) Hazardous Waste Management and (4) the SACHE certification "Basics of Laboratory Safety." Researchers must attend the annual lab refresher seminar. Other training may be required by the CHO or EH&S personnel based on the ESP review.

4) ESP approval occurs in two phases. Phase I is the preparation of a written safety plan. Upon approval of the written plan, researcher(s) may order equipment and necessary supplies, and begin to assemble experiment. Phase I also includes an evaluation by CHO (and if appropriate by EH&S) to establish controls of hazardous operations, avoid the purchase of inappropriate supplies, and establish expected waste(s) streams. Phase II approval requires evaluation of the assembled experiment, and a “dry run” of the experimental procedure or Emergency Shutdown Procedure.

“In the BR reaction the evolution of oxygen and carbon dioxide gases and the concentrations of iodine and iodide ions oscillate.  The somewhat simplified mechanism of this reaction can be represented by the following overall transformation:

IO3- + 2 H2O2 + CH2(COOH)2 + H+==> ICH(COOH)2 + 2 O2 + 3 H2O           (11.1)

This transformation is accomplished through two component reactions:

IO3- + 2 H2O2 + H+==> HIO + 2 O2 + 2 H2O                              (11.2)

HIO + CH2(COOH)2==> ICH(COOH)2 + H2O                            (11.3)

The first of these two reactions can occur via two different processes, a radical process and a nonradical process.  Which of these two processes dominates is determined by the concentration of iodide ions in the solution.  When [I-] is low, the radical process dominates; when [I-] is high, the nonradical process is the dominant one.  The second reaction (eq. (11.3)) couples the two processes.  The reaction consumes HIO more slowly than that species is produced by the radical process when that process is dominant, but it consumes HIO more rapidly than it is produced by the nonradical process.  Any HIO which does not react by eq. (11.3) is reduced to I- by hydrogen peroxide as one of the component steps of the nonradical process for reaction (11.2).  When HIO is produced rapidly by the radical process, the excess forms the iodide ions, which shut off that radical process and start the slower nonradical process.  Reaction (11.3) then consumes the HIO so rapidly that not enough is available to produce the iodide ion necessary to keep the nonradical process going, and the radical process starts again.  Each of the

NMSU CHME ESP (rev. 08/20/2015) 3

processes of reaction (11.2) produces conditions favorable to the other process, and, therefore, the reaction oscillates between these two processes.

            The detailed explanation requires attention to the individual steps of the two processes.  If iodide ions are present in sufficient concentration, the reaction follows the nonradical process, reaction (11.2).  The iodide ions react rather slowly with iodate ions,

IO3- + I- + 2 H+==> HIO2 + HIO                                     (11.4)

The iodous acid (HIO2) is further reduced to hypoiodous acid (HIO),

HIO2 + I- + H+==> 2 HIO                                            (11.5)

The hypoiodous acid is then reduced by hydrogen peroxide,

HIO + H2O2==> I- + O2 + H+ + H2O                               (11.6)

The net transformation represented by eq. (11.2) is obtained by the stoichiometric addition of eq. (11.4) + eq. (11.5) + eq. (11.6).

            Because reaction (11.2) is slower than reaction (11.3) under these conditions, so much HIO is used up by reaction (11.3) that reaction (11.6) cannot replenish the I- consumed in reactions (11.4) and (11.5); the [I-] keeps diminishing.

            Once the iodide ions have been sufficiently depleted, the nonradical process becomes very slow, and the radical process for reaction (11.2) can take over.  This process involves the five steps [3].

IO3- + HIO2 + H+==> 2 IO2

· + H2O                                    (11.7)

IO2· + Mn2+ + H2O ==> HIO2 + Mn(OH)2+                                (11.8)

Mn2+ + H2O2==> Mn2+ + H2O + HOO·                                   (11.9)

2 HOO·==> H2O2 + O2                                            (11.10)

2 HIO2==> IO3- + HIO + H+                                         (11.11)

These steps, when combined in the stoichiometry of 2 (eq. (11.7)) + 4 (eq. (11.8)) + 4 (eq. (11.9)) + 2 (eq. (11.10)) + eq. (11.11), have the overall result given by eq. (11.2).  A significant feature of this process is that, taken together, the first two steps (eqs. (11.7) and (11.8)) are autocatalytic - they produce 2 HIO2 for each one consumed.  Therefore, the rate of these steps increases as they occur.  Because this radical process is autocatalytic, it causes a rapid increase in the concentration of HIO, which is produced by the disproportionation of HIO2 (eq. (11.11)).  This process does not rapidly consume all the iodate in the solution, because the last step is second order in the catalytic species.  Thus, as its concentration increases because of the autocatalytic nature of the early steps, HIO2is ever more rapidly consumed in this last step, and the sequence of the reactions quickly reaches a steady state.

            Equations (11.8) and (11.9) indicate the function of the manganese catalyst.  The manganese is oxidized in reaction (11.8) and reduced in reaction (11.9).  Its catalytic effect in the reaction is accounted for through its providing the means for reducing IO2

·radicals to HIO2, thereby completing the autocatalytic cycle of equations (11.7) and (11.8).

            The hypoiodous acid produced by the radical process reacts with malonic acid by reaction (11.3).  However, the radical process is faster than reaction (11.3), and the excess HIO reacts with hydrogen peroxide by reaction (11.6) to create I-, which shuts off the radical process and returns the system to the slow nonradical process initiated by reaction (11.4).

            The dramatic color effects arise because reaction (11.3) does not take place in a single step, but by the sequence of reactions (11.12) and (11.13).

I- + HIO + H+==> I2 + H2O                                             (11.12)

I2 + CH2(COOH)2==> ICH(COOH)2 + H+ + I-                             (11.13)

The solution turns amber from the I2 produced through reaction (11.12), when the radical process maintains [HIO] greater than [I-].  The excess HIO is converted to I- through the reaction with H2O2 (eq. (11.6)).  The solution suddenly turns dark blue when [I-] becomes greater than [HIO], and the I- can combine with I2 to form a complex with the starch.  With [I-] high, reaction (11.2) switches to the slow nonradical process.  The color then fades as reaction (11.3) consumes iodine faster than it is produced.  When the system switches back to the rapid radical process, the cycle is repeated.

            The above reaction steps constitute a skeleton mechanism for the BR oscillating reaction.  Upon initial mixing of the solutions, IO3

- reacts with H2O2 to produce a little HIO2.  The HIO2 reacts with IO3

- in the first step of the radical process (eq. 11.7).  The autocatalytic radical process follows, rapidly increasing the concentration of HIO.  The HIO is reduced to I- in a reaction with H2O2 (eq. 11.6).  The large amount of HIO reacts with I-, producing I2 (eq. 11.12).  The I2 reacts slowly with malonic acid, but the concentration of HIO, I2 and I- all increase, because reaction (11.2) is faster than reaction (11.3).  As [I-] increases, the rate of its reaction with HIO2 (eq. 11.5) surpasses that of the autocatalytic sequence of reactions (11.7) and (11.8).  The radical process is then shut off, and the accumulation of reduced iodine is consumed by reaction (11.3) operating through the sequence of reactions (11.12) and (11.13).  Eventually [I-] is reduced to such a low value that reactions (11.7) and (11.8) become faster than reaction (11.5), and the radical process takes over again.  This oscillating sequence repeats until the malonic acid or IO3

- is depleted.

            Chloride ion concentrations in excess of 0.07 M suppress the oscillations.  Therefore the vessels used for the preparation of the solutions must be clean and distilled water must be used for all preparations.”

NMSU CHME ESP (rev. 08/20/2015) 8

Attachment 3 – Normal Operations, Startup and Shutdown Procedures

Provide a step-wise procedure that describes in detail how the work will be performed. The procedure should begin and end with the equipment in the normal idle (inoperative) state.

Include a statement of the required PPE at the beginning of the procedure, and at every location in the procedure where the PPE requirements change.

Indicate where hazardous feedstock chemicals will be stored, how they will be transported to the location of the experimental work, how they will be transferred from storage vial into the experimental apparatus, and how they will be returned to storage.

Take into account those items for which you indicate “yes” on the NMSU Lab Hazard Assessment Checklist (link found on the department website “Safety” page).

Safety: Wear proper protective equipment including chemical resistant gloves, lab coat and safety glasses when preparing and performing this demonstration. 30% hydrogen peroxide is corrosive and a strong oxidizing agent, contact with skin and eyes must be avoided. Concentrated hydrogen peroxide can cause burns. KIO3 is an oxidizer. Malonic acid solution is moderately toxic and corrosive to eyes, skin and respiratory tract. Sulfuric acid is severely corrosive to eyes, skin and other tissue. Sulphuric acid can cause severe burns, when concentrated it is a powerful dehydrating agent and generates considerable heat when diluted with water. If spilled on to the skin, care must be exercised to avoid excessive heating when flushing with water. If you have an ice bath on hand use the water from that or you can quickly remove the bulk of the liquid with a dry cloth or tissue. Flush with plenty of water and then treat the area with sodium hydrogen carbonate (NaHCO3).  Spills on the floor or bench should be neutralized with sodium hydrogen carbonate (NaHCO3) and rinsed thoroughly. The reaction produces iodine which is toxic by inhalation and irritating to eyes, skin, and respiratory tract. Perform the demonstration in a well-ventilated room.

Preparation: These should be prepared under a ventilation hood prior to the demonstration as the hydrogen peroxide loses its effectiveness over time.

1. Solution A: Prepare 100 mL of 9% H2O2 by diluting 30 mL of 30% H2O2 with 70 mL of deionized H2O. Pour into container for transport.

2. Solution B: Prepare an acidified 0.2 M KIO3 solution by adding 10 mL of 1.0 M H2SO4 to 80 mL of deionized water. Dissolve 4.3 g KIO3 in this solution and dilute to 100 mL. Pour into container for transport.

3. Solution C: Prepare starch solution by dissolving 0.1 g of soluble starch in 90 mL of boiling deionized water. When cool, add 1.5 g malonic acid, 0.4 g MnSO4•H2O, stir and dilute to 100 mL. Pour into container for transport.

Demonstration:

Add 100 mL of Solution A to a clean 500 mL beaker on the magnetic stirrer fitted with a stir bar. Next, add 100 mL of Solution B and adjust the stirring rate to produce a vortex in the mixture. Once complete, add 100 mL of Solution C and let reaction stir. Upon addition of the final solution, bubbles should appear. The solution will turn yellow then blue, then colorless. This

NMSU CHME ESP (rev. 08/20/2015) 9

reaction will oscillate for 5-10 minutes with a period which initially lasts 15 seconds but will gradually lengthen. The reaction is complete when the solution remains blue-black.

Storage and Transportation:

The solutions are to be stored in sealed glass bottles and used at the time of demonstration. Storage over long periods is not recommended because the concentrated hydrogen peroxide will lose effectiveness over time. They can be transported in any container that does not allow them to break and spill.

Clean Up:

Neutralize the iodine by reducing it to iodide. Add ~4 g sodium thiosulfate to the mixture. Stir until the mixture becomes colorless. The reaction between iodine and thiosulfate is exothermic and the mixture may be hot. Once cool, the neutralized mixture may be washed down the drain with water.

Attachment 4 -. Emergency Shutdown Procedure

Provide a step-wise procedure that describes how the equipment will be brought to a safe state in the event of an emergency. The description should include a detailed explanation of how to attend to potential medical emergencies that may result.

1. Heated stirring plate – Turn off the heat and turn of the stirrer.

2. Place all glass in an appropriate transportation storage area.

3. Neutralize the iodine by reducing it to iodide. Add ~4 g sodium thiosulfate to the mixture. Stir until the mixture becomes colorless. The reaction between iodine and thiosulfate is exothermic and the mixture may be hot. Once cool, the neutralized mixture may be washed down the drain with water.

Attachment 5 - Waste Management Procedure

Prepare a Waste Management Procedure that provides the exact nature and estimated volumes of all wastes to be generated in performing these experiments. Forward to EH&S Environmental Affairs Manager, Andrew Kaczmarek [email protected] for approval.

Attach a copy of the approval received from EH&S to this section of the ESP.

1.) Waste Chemical Waste – After the demonstration and the mixture is neutralized with sodium thiosulfate it can be disposed of down the drain to the city sewer. The drain should be washed thoroughly.

2.) KIO3 powder spill on weigh scale - Sweep up, then place into a suitable container for disposal.

NMSU CHME ESP (rev. 08/20/2015) 12

Attachment 6 – Hazard Identification and Mitigation

Identify ALL HIGH hazards associated with the experiment. The analysis must consider

all sources of energy (electric, chemical, hydraulics, mechanical, compressed gases), extreme conditions of pressure or temperature (from flame or steam to cryogenics), chemical storage, housekeeping, fire, and/or biological hazards.

Examples of HIGH hazards to include (list not exhaustive):

substances that are highly reactive, radioactive, highly flammable, pyrophoric, highly toxic, mutagenic, teratogenic, carcinogenic, or have very low exposure limits,

high voltage, high RF, x-ray, laser (class 3b or 4), high temperatures, and high pressure or pressurizing vessels.

When in doubt about whether a substance represents a HIGH HAZARD, ask for assistance.

For each HIGH hazard (use the checklist as a guide to identifying these hazards, chme.nmsu.edu/files/2013/11/Lab-PPE-selection1.pdf), provide the following information:

1. description of the HIGH hazard;

2. operational and engineering controls that will be used (based on identified industry best-practices used in addressing this safety hazard);

3. required PPE (beyond minimum) when this HIGH hazard is present; and

4. special training (beyond minimum) that is necessary.

1.) Small volume of corrosive liquids - 30% hydrogen peroxide is corrosive and a strong oxidizing agent, contact with skin and eyes must be avoided. Concentrated hydrogen peroxide can cause burns. KIO3 is an oxidizer. Malonic acid solution is moderately toxic and corrosive to eyes, skin and respiratory tract. Sulfuric acid is severely corrosive to eyes, skin and other tissue. Sulphuric acid can cause severe burns, when concentrated it is a powerful dehydrating agent and generates considerable heat when diluted with water. If spilled on to the skin, care must be exercised to avoid excessive heating when flushing with water. If you have an ice bath on hand use the water from that or you can quickly remove the bulk of the liquid with a dry cloth or tissue. Flush with plenty of water and then treat the area with sodium hydrogen carbonate (NaHCO3). Use safety glasses, chemical-resistant gloves, and lab coat.2.) Working with toxic chemicals - The reaction produces iodine which is toxic by inhalation and irritating to eyes, skin, and respiratory tract. Perform the demonstration in a well-ventilated room.3.) Possible minor chemical spill cleanup - Spills on the floor or bench should be neutralized with sodium hydrogen carbonate (NaHCO3) and rinsed thoroughly. Sweep up (KIO3), then place into a suitable container for disposal. Use safety glasses, chemical-resistant gloves, and lab coat.

NMSU CHME ESP (rev. 08/20/2015) 13

4.) Heated stir plate – Use caution in preparation of solutions on heated stir plate. May cause burns if skin comes in contact with hot plate. Use gloves and tongs when handling hot containers.

Causes gastrointestinal tract burns. May cause vascular collapse and damage. May cause damage to the red blood cells. May cause difficulty in swallowing, stomach distension, possible cerebral swelling and death. Ingestion may result in irritation of the esophagus, bleeding of the stomach and ulcer formation. Inhalation: Causes chemical burns to the respiratory tract. May cause ulceration of nasal tissue, insomnia, nervous tremors with numb extremities, chemical pneumonia, unconsciousness, and death. At high concentrations, respiratory effects may include acute lung damage and delayed pulmonary edema. Chronic: Prolonged or repeated skin contact may cause dermatitis. Laboratory experiments have resulted in mutagenic effects. Repeated contact may cause corneal damage.

Section 4 - First Aid Measures

Eyes: Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes). Skin: Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes. Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. Wash mouth out with water. Vomiting may occur spontaneously. If vomiting occurs and the victim is conscious, give water to further dilute the chemical. Inhalation: Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. Notes to Physician: Treat symptomatically and supportively. Attempts at evacuating the stomach via emesis induction or gastric lavage should be avoided. In the event of severe distension of the stomach or esophagus due to gas formation, insertion of a gastric tube may be required. To treat corneal damage, careful ophthalmologic evaluation is recommended and the possibility of local corticosteroid therapy should be considered.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear.

Clean up spills immediately, observing precautions in the Protective Equipment section. Use water spray to disperse the gas/vapor. Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Do not use combustible materials such as saw dust. Flush spill area with water. Provide ventilation. Do not get water inside containers. Keep combustibles (wood, paper, oil, etc.,) away from spilled material.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Contents may develop pressure upon prolonged storage. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Avoid contact with clothing and other combustible materials. Do not ingest or inhale. Store protected from light. Discard contaminated shoes. Unused chemicals should not be returned to the container. Rinse empty drums and containers thoroughly with water before discarding. Storage: Keep away from heat, sparks, and flame. Do not store near combustible materials. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from light. Keep away form alkalies, oxidizable materials, finely divided metals, alcohols, and permanganates. Store below 35°C. Store only in light-resistent containers fitted with a safety vent.
