<h1>BATTERIES - SEALED, GEL, AGM, VRLA, FLOODED, WET? 
</h1>
<h2>I just want a good battery – how do I choose? </h2>
<p>In order to make an informed battery buying decision, you need to understand some fundamental differences in the way batteries are constructed. These differences result in performance advantages that will be more or less important to you. The parameters may be cleanliness, ease of use, run time, initial cost, environmental factors, hazardous gases causing explosion hazards, and other criteria. 
</p>
<p>Wet batteries consist of lead plates mounted in a liquid sulfuric acid solution. Due to their internal chemical reactions and heating during charging, they inherently lose water that must be replaced through regular maintenance, or damage to the batteries will occur. 
</p>
<p>Gel and AGM batteries belong to a family of batteries called VRLA, or Valve Regulated Lead Acid. They are sealed and do not lose water during charging, and therefore are referred to as being “maintenance free.” Although wet and VRLA batteries are similar in key design fundamentals (a lead surface and a sulfuric acid electrolyte), they differ in construction and application. 
</p>
<h2>Wet / Flooded Batteries</h2>
<h3>Advantages</h3>
<ul>
 <li>They have the lowest cost for a given runtime/amp hour</li>
 <li>They tend to have the longest life span if properly maintained and not abused.</li>
 <li>Most use Lead-Antimony plates, which have improved plate strength, an important feature for electrical vehicles that are subject to abrupt stops and starts, bumps, and vibration.</li>
 <li>They can tolerate frequent charge/discharge cycles</li>
</ul>
<h3>Disadvantages</h3>
<ul>
 <li>Lead-Antimony plates, although stronger than the Lead-Calcium plates used in VRLA batteries, inherently have a much higher self-discharge rate. This means that wet batteries cannot be stored for any length of time without supplemental charging to make sure the plates do not sit in a discharged state, which will allow sulfation, battery degradation, and premature battery failure. 
</li>
 <li>Care must be taken while handling wet batteries so as not to expose personnel, other equipment, or delicate surfaces to sulfuric acid that may spill when the fill ports are uncapped or if the battery tips. </li>
 <li>During the charge process, an explosive mixture of oxygen and hydrogen is produced that may accumulate in pockets outside the battery, so wet batteries need to be properly ventilated and are subject to shipping restrictions.</li>
 <li>They must be kept in an upright position to prevent leaking and spilling</li>
 <li>There are associated costs and inconveniences related to the required regular servicing needs of wet batteries, such as damaged and/or special clothing, hazardous material handling and transport requirements, shipping restrictions, damage to service areas from acid, and other personnel-related costs that should be considered when choosing a battery.  However, by far the biggest cost is incurred by not maintaining the batteries. </li>
 <li>Freezing – A fully discharged wet lead acid battery will freeze at temperatures close to -10°F.  The expansion of the electrolyte can damage the plates, separators or even crack the battery case.  If freezing should occur, you must let your battery thaw, physically inspect the case for leakage, fully recharge it in a well ventilated area, remove the surface charge, and load test the battery and charging system to determine if there is any latent or permanent damage. </li>
</ul>
<h2>Valve Regulated Lead Acid (VRLA) Batteries</h2>
<ul>
<li>Encompass both gelled electrolyte (gel) and absorbed glass mat (AGM) batteries. </li>
<li>Battery housing is sealed with pressure relief valves that typically cannot be modified or removed.</li>
<li>No maintenance – you do not add water to the cells.</li>
<li>According to industry experts, the shelf life of a VRLA battery is seven times higher than the shelf life of a comparable wet battery. </li>
</ul>
<p>To avoid damaging your batteries, do not mix wet and VRLA batteries on the same machine! </p>
<p>Overcharging is especially harmful to VRLA batteries because it dries out the electrolyte by driving the oxygen and hydrogen out of the battery through the pressure relief valves, where it cannot be recovered. A battery can be overcharged even though it is not fully “charged”. That is why using the proper charger and charger algorithm is critical for battery performance. 
</p>
<p>Battery manufacturers consider the battery warranty void if improperly charged.</p>
<h2>Gelled Electrolyte Batteries </h2>
<p>Gelled batteries contain sulfuric acid that has been gelled by the addition of Silica gel, turning the acid into a solid mass the consistency of petroleum jelly that coats the lead plates. 
</p>
<h3>Advantages</h3>
<ul>
 <li>Gelled batteries are sealed, have special pressure relief valves and should never be opened.</li>
 <li>Since they require no maintenance, they don't have the costs and inconvenience of regular servicing associated with wet batteries. </li>
 <li>It is impossible to spill acid even if the battery case is broken; therefore it can be operated in virtually any position other than upside down.</li>
 <li>They are very safe at sea - no chlorine gas can form due to sulfuric acid and salt water mixing.</li>
 <li>Gelled batteries can be stored at sub-freezing temperatures as low as -25° to -35°F, as long as they are fully charged prior to storage.</li>
 <li>Gelled batteries use a recombination reaction to prevent the escape of hydrogen and oxygen gases that are normally lost in wet batteries under normal operating conditions.  However, the batteries should still be ventilated.</li>
 <li>Because of their “acid-starved” design, gelled batteries are better suited for deep-discharge applications that would otherwise damage the plates of wet or some standard AGM batteries (not the Discover AGM batteries offered by Nilfisk-Advance).</li>
 <li>According to industry experts, the chance of explosions for gel batteries is as little as 1 in 1,000,000 compared with 1 in 1,000 for wet acid batteries.</li>
</ul>
<h3>Disadvantages</h3>
<ul>
 <li>Gel batteries must be charged at a slower rate to prevent excess gas from escaping and damaging the cells.</li>
 <li>They must be charged at lower voltages than flooded or AGM.  If overcharged, voids can develop in the gel which will never heal, causing a loss in battery capacity. </li>
 <li>Although gel batteries are sealed, there is some water loss. In hot climates, water loss can be enough over 2-4 years to cause premature battery failure.</li>
 <li>Their initial cost is higher than wet batteries for a similar amp hour capacity</li>
 <li>They are heavier than comparable wet batteries. </li>
</ul>
<h2>AGM Batteries </h2>
<p>Absorbed Glass Mat batteries utilize a very fine fiber Boron-Silicate glass mat between the plates.  This mat can take more abuse than gel. 
</p>
<h3>Advantages</h3>
<ul>
 <li>AGM batteries are sealed, have special pressure relief valves, and should never be opened. </li>
 <li>Since they require no maintenance, they don't have the costs and inconvenience of regular servicing associated with wet batteries. </li>
 <li>The sulfuric acid cannot spill, even if the battery is severely overcharged or broken, because it is contained in the glass mats</li>
 <li>no chlorine gas can form due to sulfuric acid and salt water mixing. </li>
 <li>AGM batteries can be stored at sub-freezing temperatures as low as -25° to -35°F, as long as they are fully charged prior to storage.</li>
 <li>Most types are recombinant, where Oxygen and Hydrogen recombine inside the battery – this results in efficiency of over 99% and almost no water loss. </li>
 <li>Internal resistance is extremely low, so there is almost no heating of the battery during the charging process. </li>
 <li>AGM batteries have a very low self-discharge – from 1 – 3% per month, so they can sit without charging in storage for much longer periods without damage than wet batteries.</li>
 <li>Since the lead plates are tightly packed and rigidly mounted, AGM batteries withstand shock and vibration. </li>
 <li>AGM batteries excel for high-current, high-power applications and in extremely cold environments. </li>
 <li>Compared with the same size gel battery, AGM's will have a higher amp hour rating and therefore deliver longer run times.</li>
 <li>Classified as non-hazardous, thus their shipping costs are lower.</li>
 <li>They don't have the maintenance costs associated with wet batteries.</li>
</ul>
<h3>Disadvantages</h3>
<ul>
 <li>AGM batteries cost 2 to 3 times as much as flooded batteries of the same capacity. </li>
 <li>Where there is adequate ventilation and no leakage concerns, flooded batteries are a better economic choice. </li>
 <li>AGM batteries can be susceptible to thermal runaway during charging because of their recombination reaction. This is another reason why it's so important to match batteries with the appropriate charger and algorithm. </li>
</ul>
<h3>CAUTION!</h3>
<p>Lead-acid batteries contain sulfuric acid, a highly corrosive poison that may produce explosive gasses when the battery is recharged. This can hurt you! Therefore, when charging or working with batteries: 
</p>
<ul>
 <li>Make sure they are well ventilated. If accessible, open the machine battery compartment cover or seat and leave it open during the charging process.</li>
 <li>Remove your jewelry, wear safety goggles, protective gloves, and clothing.</li>
 <li>Be careful with your tools so you don't drop a metal tool across exposed battery terminals – the resultant spark may cause an explosion.</li>
 <li>Do not allow battery electrolyte to mix with salt water. Even small quantities of this combination will produce chlorine gas that can kill you. </li>
 <li>Refer to the Charging Do's and Don'ts section for more instructions on charging specific battery types. </li>

 <h3>STERILE HYPHAE</h3>
 <p>Fungus that did not produce spores in the laboratory culture; without sporulation a formal scientific classification cannot be determined. </p>
 <h3>BACTERIA</h3>
 <p>Most environments (air, water, and solid surfaces) contain a variety of bacterial organisms. The type and concentration of bacterial organisms present are influenced by the prevailing conditions. Bacteria are microscopic parasites that are from one to five micrometers in size and that can live on living or nonliving organic (carbon compounds) in the presence or absence of oxygen. Bacteria excrete complex biochemical products that are instrumental in the decay of nonliving matter. A few bacteria are Obligate Pathogens that require a living host, however, most bacteria are Facultative Pathogens that can live on living or nonliving matter.
 </p>
 <p>Gram staining allows for the separation of bacteria into two groups: Gram positive (+) or Gram negative (-). Cocci are very small sphered, while the rods can be spiral (spirilla) or straight (bacilli). </p>
 <h3>FUNGAL SPORE LEVELS</h3>
 <p>References site the comparison of outdoor and indoor concentrations as a means to evaluate indoor microbiological contamination. In 1987, the ACGIH (American Conference of Governmental Industrial Hygienists) stated that indoor fungal counts should be less than half of the outdoor level for a mechanically ventilated building. Fungal concentrations of 1000 cfu/m3 have historically been reported as being tolerable for an indoor environment (Morey 1984, and Breif and Bernath 1988), however more recent data suggest that the health effects from the inhalation of these spore quantities may be severe enough to recommend considerably lower tolerance limits (Etkin 1994). Indoor airborne samples should contain less than 300 cfu/m3 of the common fungi Cladosporium and less than 150 cfu/m3 of all other mixed species of fungi (Miller 1988). Fungal spore levels in excess of 500 cfu/mc in winter indicate that a building or residence has abnormal sources and/or insufficient ventilation (Reponen 1990).  
</p>
<p><b>Contamination levels of non-specific allergenic, pathogenic, or toxic fungal spores </b></p>
 <p>Mold contamination is considered present in a building when the total mold spore concentration per cubic meter is above 10,000. (Baxter, ETS).  
</p>
 <p>The National Allergy Bureau considers mold counts in air of 0-900 as low, to 2,500 as moderate, to 25,000 as high, and above 25,000 as very high. At “high” levels most individuals with any sensitivity will experience symptoms. Acceptable levels for individual species vary since species toxicity varies widely as does spore size, weight, and other features which affect risk to building occupants. Eg. Aspergillis/Penicillium in a “clean” residential building study was at a mean of 230, in buildings known to have a moisture or flooding problem it was at 2,235 and in mold contaminated buildings the figure was 36,037.

Common Molds

<h1>COMMON AIRBORNE PARTICULATES</h1>
 <p>Particulate contamination or simply “dust”. Dust contamination exists in a variety of concentrations, size distribution, and compositions. The characteristics of dust are very dependent upon the dust sources. It is very common to find clothing fiber, dirt and construction materials in most facilities. </p>
 <p>Less common dust sources also exist. Natural events, such as volcanic eruptions and dust storms are some of the largest dust producing events possible. These events introduce a variety of different constituents into the atmosphere that usually remain airborne for considerable periods of time. In addition to natural events, specific industries may generate their own particulate contamination.  </p>
 <p>Particulate contamination can have one or more of the following characteristics:</p>
 <ul>
 <li>Abrasiveness: abrasive particulate may contribute to wear as well as fretting and fretting corrosion. </li>
 <li>Hygroscopic: many particulate contamination compositions have an affinity for water and readily absorb water vapor in the air. If sufficient water vapor is available, the particulate can become wet with water at temperatures above the bulk room dew point.  </li>
 <li>Corrosive Composition: the elemental composition of a particulate contamination may be corrosive to materials within electronics. </li>
 </ul>
 <p><b>Synthetic Fibrous Particulate</b>: Common sources include clothing, carpet fibers, insulated drop in ceiling tiles, insulation. </p>
 <p><b>Common sources</b>: Clothing </p>
 <p><b>Other sources</b>: Carpet fibers, insulated drop in ceiling tiles, and insulation. Because synthetics have a low melting point, they may create a sticky surface to which other particulates will adhere.</p>
 <p><b>Metallic Particulate</b>: Metal dust enters the environment from a variety of sources. Common culprits include worn air conditioning parts, new raised floors, rotor brushes in vacuum cleaner monitors and printer component wear. Another common culprit is the electrician, who might be hardwiring and leave metal debris behind. Metallic particulates conduct electricity. Because they conduct electricity, they have an increased potential for creating short circuits in electronics. They are also magnetically attracted to circuits because of the magnetic fields generated by computer equipment. This particulate usually shows up as rust. </p>
 <p><b>Carbonaceous Particulate</b>: Carbon comes from automobile exhaust, tobacco smoke, printer toners and carbon paper dust. In addition to being conductive, carbon dust is also combustible in sufficient concentrations.</p>
 <p><b>Fibrous Organic Particulates</b>:  These are natural based fibers such as cotton and wool. These fibers usually originate from clothing, but also from incorrect cleaning materials or packaging materials. These fibers absorb moisture and can cause major problems with electronic circuits.</p>
 <p><b>Paper Dust</b>: Paper dust and particulates can cause problems similar to the fibrous particulates. These particulates are attracted to magnetic fields.</p>
 <p><b>Concentrations of any of these particulates in sufficient quantities can be considered a health hazard, although any serious cause for concern would be indicated by a visible manifestation of the contaminant, either airborne observation, or by accumulation on horizontal surfaces.</b></p>

<h1>NO-TOUCH SYSTEMS CAN LEAD TO CLEANER RESTROOMS</h1>
<p>E-coli outbreaks. Resistant bacteria. New infectious diseases. People today are confronted with news about the consequences of poor hygiene and the spread of germs on an ongoing basis. And one of the places where hygiene can be improved is the restroom.</p>
<p>While proper hand washing is the most effective means of preventing germ transmission and cross-contamination, numerous studies have shown that large numbers of people don't wash after using the restroom. As a result, someone who is infectious can potentially spread germs to others via restroom fixtures, surfaces, faucets and product dispensers. So it stands to reason that when your staff comes to work, they deserve nothing less than a clean and sanitary restroom. A clean and sanitary restroom lets staff know that management is paying close attention to one of the building's most important areas. Conversely, a dirty or disorderly restroom is not only an eyesore but may heighten fears of germ transmission.</p>
<p>While it can sometimes be difficult to achieve restroom hygiene, particularly in high-traffic locations that require frequent restocking, there are systems on the market that can greatly assist property managers in reaching this goal. Among them: No-touch systems. </p>
 

<p>A vast array of products are available today that require no-hands operation or contact only with the product, not with dispenser handles or levers. No-touch systems can include everything from sensor-activated faucets and toilet flushing devices to card-entry devices that allow someone to enter the restroom without even touching the door. </p>
 <p>Other types of no-touch products include enclosed bathroom tissue and paper towel systems that enable users to touch only the product they will be using. These enclosed systems reduce the potential for cross-contamination because users touch only the product they use. Since the product is enclosed it is also protected from dirt and moisture.  In addition, towel and tissue products that offer controlled dispensing reduce litter and paper debris, which, while not necessarily unsanitary, conveys the appearance of an unclean restroom environment. </p>
<h3>Don't Forget Soap</h3>
<p>Another important area that can impact restroom hygiene is soap. Even though soap is a small cost component 
 
of a restroom, it is frequently a prime area of complaint. One study of people's hand washing habits found that nearly 
 
half the people who did not wash with soap after using the restroom had no choice — there was no soap. This can 
 
be particularly disconcerting to the person who wants to “do the right thing” but can't. So it's important to offer 
 
high-capacity or dual cartridge soap systems that last longer and work properly. 
</p>
<p>Using a concentrated, clear antibacterial soap can help reduce germs while adding level of comfort for people 
 
accustomed to using similar products at home. A thicker, concentrated soap provides a rich feel, adding to an overall 
 
impression of quality that can improve perceptions of the restroom. And, here too, no-touch systems can be used to 
 
help prevent the spread of germs via cross-contamination. 
 
</p>
<h3>Cleaning Systems</h3>
<p>As restroom products manufacturers have moved to touchless products and systems, so, too, have manufacturers of cleaning systems. Some systems provide on-demand sanitizing and cleaning of fixtures based upon flushing. There are also no-touch cleaning products that enable housekeeping professionals to clean without touching any surface in the restroom with their hands. These systems are also simple to operate as they consist primarily of electrical pressurized spraying systems mounted on a cart with a spray wand. In addition to physical cleanliness, the systems help restrooms look and smell fresh and clean. </p>
<p>With these and other tools it is easier than ever before to create a hygienic, sanitary restroom environment for your staff. When you consider how much time the average person spends in the restroom — more than three workdays a year — doing anything less just doesn't make sense.</p>
</div>
Benefits Of No-touch Systems
A 
Abrasion:  The  wearing  away  or  cleaning  by  friction. Abrasion can also relate to the wearing away of a floor 
finish film by friction.

Abrasive: A product that works by abrasion. Products such as cleaners, polishes, and pads may contain an abrasive.

Acid: A chemical substance with pH less than 7 that reacts with and neutralizes an alkali.

Acidity: A measure of the strength of an acid. See pH and Alkalinity. 

Acrylic: Type of polymer used in floor finishes. Also, a man: made synthetic fiber used in spun yarn to resemble wool in carpet
Active Ingredients: The ingredients in a product that are specifically designed to achieve the product performance          objectives
Acute Toxicity: The short-term toxicity of a product in a single dose.Can be divided into oral, cutaneous, and respiratory toxicities. 
Adhesion: A necessary characteristic of a floor finish, which causes it to bond to the floor rather than peel, flake or powder. 
Adsorption:  Adsorption  is  a  surface  phenomenon that  some  products  exhibit,  whereby  they  form  a 
physicochemical  bond  with  substances.  Not  to  be confused with absorption.

Aerobic  Bacteria: Bacteria  that requires oxygen. Pseudomonas is an example.

Aerosol  Spray:  A  means  of  atomizing  liquids  by propelling them from a pressurized container by a soluble gas

Air Pollution Potential: Products may contain volatile organic  compounds  (VOC).  When  these  products  are used, the VOCs may escape to the atmosphere and react to form smog. Smog and other atmospheric pollutants have been shown  to cause irritation of the eyes, nose, 

Acute Effect: Adverse effect on a human or animal that has  severe  symptoms  developing  rapidly  and  coming 
Quick to crisis. See also CHRONIC, throat, lungs, and cause asthma attacks. Many state and local authorities have restrictions on the use of VOCs.  This issue can also be a problem with indoor air from chemicals including cleaning products.
