storage facility. When the appropriate pressure is reached, the internal valve is opened to allow the product to flow through the hose. There are two pressure gauges, one located at the front of the tank and the other next to the dome lid. When the tank is empty of the product, these gauges will gradually return to zero as the built-up pressure escapes through the hose. The valves are then shut off at the customer’s end and at the tank end. The compressor is turned off and the hose is unhooked. The Christmas tree valve is opened to bleed off the small amount of air pressure that may be left. With this method, the dome lid must be tightly sealed.
On November 12, 1980, Sylvester, Klipsch’s driver, arrived at Dennis’s gate and turned over the tank trailer to Steen-rod. Steenrod drove the tank trailer into Dennis’s plant and positioned it over the storage facility. Steenrod sampled the product in the tank trailer by opening the dome lids for each compartment on top of the tank. He remembered seeing a warning sign on the dome lid that said something to the effect, “Danger do not open under pressure.” He then proceeded to attempt to unload compartment no. 1 by the liquid pump method. Steenrod was unable to unload by this method because he could not find the necessary fittings. Thereafter, Steenrod decided to use the pressure method.
To build up pressure, Steenrod turned on the compressor and opened up the external and Christmas tree valves. While the compressor ran, Steenrod continued to look for fittings so that he could revert to the pump method. About this time, Bigby saw Steenrod and talked to him. According to Bigby, Steenrod said that he was using air pressure to “blow off the load,” which did not seem to be working. Bigby recalled Steenrod being concerned that pressure was building in the tank, but that he could not locate the pressure gauge to confirm this fact.
Steenrod’s search turned up enough fittings to revert to the pump method. Steen-rod proceeded to turn off the compressor, which, at that point, could have been running for up to four hours. According to Steenrod’s deposition testimony of December 1981, which was read at trial, he then hooked up one hose, went up on top of the tank to open the dome lid, and “that’s when it blew up.” Steenrod testified at trial to a conflicting set of events that resulted in the dome lid blowing open. The blast caused Steenrod to be thrown to the ground, which resulted in his injuries.
Subsequently, Steenrod filed an action in negligence against Klipsch on July 6, 1981. After starting trial on this action, the trial court granted his motion to dismiss without prejudice on November 13, 1984. On November 8, 1985, Steenrod refiled his petition in five counts, subsequently amending his petition six times between November 8, 1985 and October 14, 1988. On October 31, 1988, the first day of trial, Steenrod attempted to amend his petition for a seventh time. After objection from Klipsch that an amendment would cause further discovery and delay, the trial court refused leave to amend.
Since several of Steenrod’s points on appeal concern the discovery proceedings in his action, we shall set forth these pretrial events. The cause originally was set on the trial docket of January 19, 1988. Due to Steenrod’s request for removal of the case because he needed additional time to hire an expert, the cause was reset for trial on February 29, 1988. Thereafter, on January 27, 1988, the cause was removed and reset on the July 5, 1988 docket, again at the request of Steenrod because he was unable to hire an expert.
On January 27, 1988, the court also entered an order requiring Steenrod to disclose all experts and make them available for deposition by opposing counsel. Steen-rod partially complied with this order and designated four experts. On April 5, 1988, two experts were stricken pursuant to Klipsch’s motion to strike, and a third expert was later withdrawn. On May 4, 1988, the remaining expert, Dr. Ben Bayse, was stricken pursuant to Klipsch’s motion on the ground that Dr. Bayse had failed to provide adequate discovery.
