Darla is in the pest control business. She develops and produces fumigation gas for her own use. She also sells the gas to consumers. Some of her competitors do not sell gas to consumers because consumers sometimes do not follow safety instructions.

Darla sold a container of fumigation gas to Albert for use in ridding his apartment of insects. Although she had intended to produce gas of standard toxicity, she had unknowingly produced gas of unduly high toxicity. Albert used the gas and succeeded in killing all the insects in his apartment. Because he used the gas carelessly, some made their way into his neighbor's apartment, Paul. The gas caused Paul to suffer serious lung damage and fear that he would contract cancer.
